For Europe and North America: sea freight (FCL/LCL) for bulk orders, air freight (FedEx/DHL) for urgent and sample shipments. For Southeast Asia (Singapore, Malaysia, Thailand, Vietnam): sea freight is fast (3–7 days from Shanghai/Ningbo), and we have existing customer relationships in these markets. All export documentation (packing list, CoA, SDS, origin certificate) is provided in English.
A：For standard specifications in stock: 1–2 weeks. For standard specifications requiring production runs: 3–5 weeks. For custom specifications (non-standard dimensions, special surface treatment, or custom colors): 5–8 weeks. Lead times can be shortened for urgent orders with pre-arrangement — please discuss with our sales team. We maintain safety stock of our most popular semiconductor-grade ETFE HP and FEP HP rolls to support rapid prototype and qualification orders.
A：Yes. All production rolls pass through our online optical defect detection system that identifies pinholes, gel particles, streaks, and edge defects at high resolution across the full film width. Our standard acceptance criteria for semiconductor-grade lots are zero tolerance for pinholes >0.5mm and gel particles >1mm per 10m²·roll segment. Tighter specifications can be agreed upon for specific applications. Defect maps are available upon customer request for critical lots.
A：Shelf life is 24 months from the production date under recommended storage conditions: temperature 15–35°C, relative humidity below 80%, away from direct UV exposure and heat sources. Rolls should be stored in their original packaging (PE wrap) on a horizontal axis, not standing upright. Fluoropolymer films are chemically stable and do not degrade under these conditions. Surface-treated lots (plasma-treated) should ideally be used within 6 months of treatment to maintain peak surface energy.
A：Yes. We support the qualification process for semiconductor and electronic component customers, including preparation of First Article Inspection (FAI) reports, PPAP (Production Part Approval Process) documentation packages, control plans, process FMEAs, and measurement system analysis (MSA). Our quality management system (certified to IATF 16949 and AS9100) is designed to support these formal qualification processes. Please contact our technical sales team to initiate a qualification project.
A：Fluoropolymer films — particularly PTFE, ETFE, FEP, and PFA — exhibit very low outgassing. PTFE meets NASA's ASTM E595 standard (TML <1%, CVCM <0.1%). Our ETFE HP and FEP HP films, produced from 100% pure resin without plasticizers, demonstrate similarly low outgassing characteristics. For vacuum chamber applications or where ionic/organic contamination must be minimized, third-party ASTM E595 testing can be arranged. Data sheets on thermal stability and decomposition thresholds are available upon request.
A：Yes, Safety Data Sheets (SDS) are available for all our film products (ETFE, FEP, PFA, PVDF, PEEK) in English, and in other languages upon request (Chinese, Japanese, Korean, German, etc.). Fluoropolymer films are classified as non-hazardous materials under normal handling conditions. Processing above the melting point should be done with adequate ventilation as per SDS guidance. SDS documents are provided with every first shipment and are available for download through our sales team.
A：All our fluoropolymer films (ETFE, FEP, PFA, PVDF, PEEK) are RoHS 2 compliant — they contain none of the restricted substances including lead, mercury, cadmium, hexavalent chromium, PBBs, or PBDEs. They comply with EU REACH SVHC (Substances of Very High Concern) requirements. SGS testing has been conducted to verify compliance. Full material declaration (FMD) documentation is available. We also confirm compliance with halogen-free standards where ETFE and other fully fluorinated grades are used.
A：Yes. Our ETFE HP film has a UL-94 V-0 flame rating, verified by UL certification. ETFE has a Limiting Oxygen Index (LOI) of 31%, meaning it does not sustain combustion in normal air and self-extinguishes rapidly. No brominated or chlorinated flame retardants are used — the flame resistance is inherent to the fluoropolymer chemistry. UL Yellow Cards and certification documentation are available upon request for your qualification and regulatory compliance needs.
A：PEEK and ETFE films are well-suited for test socket and burn-in board applications. PEEK's high-temperature stability (UL RTI 240°C), low dielectric constant (3.2–3.3), and excellent dimensional stability under repeated thermal cycling make it the preferred insulation film for probe card substrates and high-temperature test socket components. ETFE offers superior electrical insulation (UL-94 V-0) with higher flexibility for dynamic applications like ribbon connectors in test handlers.
A：Yes. Our ETFE and FEP films can serve as protective top cover films during blade dicing or laser dicing of wafers. The film protects the device surface from dicing debris, coolant contamination, and mechanical stress. After dicing, the film is peeled off cleanly without leaving adhesive residue. Plasma-treated grades provide temporary hold during the dicing process, while untreated grades act as non-contact shields. Film thickness of 50–75μm is typically specified for this application.
A：In thermal diffusion and oxidation furnace environments, PFA and FEP tubes and films are used as wafer boat end caps, furnace tube liners, and protective covers for quartz components. Our PFA HP film (260°C long-term rating) is the material of choice for components inside diffusion furnaces where temperatures can reach 200°C in the loading zone. Its zero contamination profile — no metallic ions, no halide release — ensures process integrity during dopant diffusion and gate oxidation.
A：FEP and ETFE films offer excellent optical clarity (>90% solar transmittance) and low haze, making them suitable as pellicle-support membranes and protective windows in photolithography systems. Their near-zero moisture absorption prevents dimensional change during exposure. The stable dielectric constant of FEP (2.1) and absence of ionic contaminants are critical for protecting photoresist integrity. Our films can be supplied in ultra-thin grades (down to 12.7μm) required for pellicle applications.
A：Our FEP and PFA films are highly resistant to the acidic and alkaline slurries used in CMP: silica or ceria abrasive slurries, KOH-based slurries (pH 10–11), and HNO₃-based slurries. They are used as protective linings in slurry delivery systems, polishing head components, and as membrane materials in retaining rings. PFA is especially suitable due to its high chemical purity and resistance to oxidizing agents present in oxide CMP slurries.
A：In die attach processes, fluoropolymer films serve as release carriers for die attach film (DAF) lamination and as protective sheets during pick-and-place operations. In wire bonding, our ETFE and PEEK films are used as isolation layers on bond pads and as protective shields during ultrasonic bonding to prevent contamination. Their low ionic content and zero halide leaching ensure no impact on bond wire reliability or adhesive curing.
A：In wet processing equipment, our FEP and PFA films are used as lining materials and protective films for etch baths (HF, BOE, H₂SO₄/H₂O₂ piranha, SC-1, SC-2), rinse tanks, and chemical delivery systems. Their near-zero permeability prevents contamination of ultra-pure chemicals. PFA is preferred for the highest-purity applications. Our films are also used as protective covers on wafer-holding fixtures and boat carriers during wet etching to prevent metallic contamination.
A：Fluoropolymer release films are used across a wide range of package types: QFN (Quad Flat No-lead), BGA (Ball Grid Array), CSP (Chip Scale Package), LGA (Land Grid Array), WLCSP (Wafer-Level Chip Scale Package), power modules (DBC substrates), MEMS packages, and SiP (System-in-Package). The trend toward thinner packages and fine-pitch interconnects is increasing demand for higher-precision release films — an area where our ETFE HP series excels.
A：The most commonly used thickness range for FAM release film is 50–100μm. Thinner films (50–75μm) provide better mold-cavity conformability and sharper feature reproduction in fine-pitch packages (QFN, BGA, CSP). Thicker films (75–100μm) offer slightly longer per-roll service life and are preferred for larger packages. We offer ETFE HP in this full range and can customize to your specific mold geometry and cycle pressure requirements.
A：Our PEEK film (melt-extruded casting) has a melting point of 340°C, UL RTI rating up to 240°C, tensile strength 60 MPa, elongation at break 300%, and thermal shrinkage (MD) of only 0.25%. Width up to 380mm, thickness 45–48μm, in yellow and black. In semiconductor applications, PEEK is used for high-temperature flexible circuit insulation, probe card substrates, and as a carrier film in tape-and-reel packaging for temperature-sensitive components.
A：Choose PFA HP when your process requires continuous service at temperatures above 205°C — PFA HP's rated long-term temperature is 260°C (vs. FEP's 205°C), with a melting point of 302–310°C. PFA is also preferred for ultra-clean wet chemical handling (HF, H₂SO₄, HNO₃) in etch baths and chemical delivery lines because it has marginally better chemical resistance than FEP. PFA's lower melt viscosity also makes it easier to form into complex shapes for wafer carriers and fittings.
A：FEP HP has a dielectric constant of approximately 2.1 (stable across frequency and temperature), a dielectric strength of 6,500 V/25μm (ASTM D149), and a volume resistivity exceeding 10¹⁸ Ω·cm. These properties make it ideal for high-frequency circuit board insulation, antenna substrates, and RF filter components. Its melting point is 260°C and long-term service temperature 205°C — well above typical semiconductor process temperatures.
A：Key specs: specific gravity 1.74; flame rating UL-94 V-0; water absorption <0.03%; tensile strength 48 MPa (ASTM D882); elongation at break 300%; tensile modulus 965 MPa; long-term service temperature 165°C (UL-746B); melting point 260°C; solar transmittance >90% (ASTM E424). Width: 25–1,600mm standard, up to 2,100mm custom. Thickness: 12.7–500μm. Available with plasma or chemical etch surface treatment for enhanced adhesion to EVA or encapsulants.
A：Our ETFE HP series is produced from 100% high-purity ETFE resin with no additives, fillers, or plasticizers. This is critical in semiconductor manufacturing because any ionic or metallic contamination — even at parts-per-billion levels — can cause device failure. The water absorption of ETFE HP is below 0.03%, meaning moisture-induced outgassing during molding (which can create voids or delamination in packages) is minimized.
A：ETFE offers the best balance of mechanical toughness, flexibility, and release performance for Film-Assisted Molding (FAM). Its tensile strength of 48 MPa and elongation at break of 300% allow it to conform tightly to complex mold cavities without tearing. Compared to PTFE, ETFE is more dimensionally stable under the heat and pressure of transfer molding cycles (typically 175–180°C). Our VitaFlon®ETFE HP is made from 100% high-purity resin with no plasticizers, ensuring zero contamination to the device.
A：PLUSXTECH supplies ETFE HP (ultra-pure grade), FEP HP (high-purity grade), PFA HP (high-purity grade), PVDF, and PEEK films for semiconductor applications. Each is produced via precision melt-extrusion casting with strict purity controls. The ETFE HP series is especially popular as a molding release film for IC packages, while FEP and PFA are used in wet-process equipment linings and wafer carriers.
A：Yes, our ETFE and PTFE films serve as carrier and release substrates in printed electronics manufacturing: as temporary substrates for printed circuit deposition, as release layers in roll-to-roll gravure and inkjet printing of flexible electronics, and as protective cover films during flexible display lamination. Their dimensional stability and smooth surface ensure precise registration of printed patterns.
A：We currently ship globally from our manufacturing bases in Hubei, China. We are actively building distribution partnerships across Europe, North America, and Southeast Asia to reduce lead times and improve local support. If you are interested in becoming a regional distributor or stocking partner, please contact our international business development team.
A：Our standard PTFE films are available in natural (translucent white/milky), red, and blue colors. Natural PTFE has moderate translucency — sufficient for general process visibility. For applications requiring clear inspection through the film, we recommend our ETFE or FEP films, which offer >90% optical transmittance. The colored variants (red/blue) are used for identification in multi-layer processes.
A：Yes, our PTFE and ETFE films are suitable for solid-state battery electrolyte manufacturing processes. They serve as release substrates for thin-film electrolyte casting (sulfide, oxide, and polymer electrolytes), as carrier films for transfer-printing solid electrolyte membranes, and as separator films during hot-press lamination of solid-state cell stacks. Their chemical inertness to sulfide electrolytes is particularly valuable.
A：Rolls are wound on cardboard or plastic cores, individually wrapped in PE film, and packed in cartons or wooden pallets for export. Each roll is labeled with product grade, lot number, dimensions, and production date for full traceability. Storage conditions: temperature 15–35°C, humidity <80% RH, away from direct sunlight and UV sources. Shelf life is 24 months under proper conditions.
A：Yes, we offer PTFE films starting from 25μm (MR1 series). Our thinnest PTFE is 25μm (MR1), available in widths up to 1,220mm. For applications requiring even thinner fluoropolymer films, we recommend our ETFE or FEP series starting at 12μm. Ultra-thin PTFE skived film (down to 6μm) is available for specialized applications — please inquire.
A：PTFE exhibits very low outgassing in vacuum environments, meeting NASA's ASTM E595 standard (Total Mass Loss <1%, Collected Volatile Condensable Material <0.1%). This makes our PTFE films suitable for space applications, vacuum chamber components, and high-vacuum processing equipment. Low-outgassing grades can be specified for critical vacuum applications.
A：Yes, PTFE films are used as processing aids in GDL production. During the PTFE dispersion coating and sintering process for carbon paper or carbon cloth GDL, our release films serve as the carrier substrate that is peeled off after coating, and as the release surface on press platens during hot-pressing. Their thermal stability up to 380°C (PTFE sintering temperature) is essential.
A：We offer comprehensive OEM and private label programs for international partners: custom labeling (your brand name and logo on rolls), custom packaging (box and reel configurations), custom documentation (datasheets and SDS in your preferred language), and exclusive territory arrangements for qualifying distributors. Please contact our international sales team to discuss partnership opportunities.
A：PTFE's low surface energy makes direct bonding challenging. Recommended methods: (1) Chemical etching (sodium naphthalene etching) creates reactive surface sites; (2) Plasma treatment improves wettability; (3) Mechanical bonding (expansion into sintered or porous metal substrates). After etching, standard epoxy or polyurethane adhesives bond well. We supply pre-etched PTFE for bonding applications.
A：Both PTFE and ETFE have outstanding UV resistance. PTFE is essentially transparent to most UV wavelengths and undergoes no photodegradation. ETFE absorbs some UV but is specifically engineered with UV-stable chemistry and does not yellow or embrittle over 25+ years of outdoor exposure. Both materials outlast typical UV-absorbing polymers (PVC, PC, PE) by a significant margin.
A：ETFE-EC uses acrylic PSA instead of silicone PSA, and operates at -150°C to +165°C (vs. PTFE's -70°C to +260°C). Choose ETFE-EC when: (1) you need stronger long-term bonding (acrylic PSA has higher cohesive strength), (2) your max temperature does not exceed 165°C, or (3) your application requires better performance in low-temperature environments (down to -150°C). Choose PTFE tape for higher temperature applications.
A：Yes, PTFE film makes an excellent high-performance release liner for PSA tape and label manufacturing. Its ultra-low surface energy provides very low release force for aggressive PSA formulations, and it maintains liner integrity during the die-cutting and winding processes. It is preferred for specialty tapes where silicone-release paper would contaminate the adhesive or fail at temperature.
A：Standard PTFE has low thermal conductivity (~0.25 W/mK), making it a thermal insulator rather than a conductor. However, thermally conductive PTFE composites filled with ceramic or graphite fillers are available and can serve as flexible thermal interface materials. For standard release applications in electronics, the low thermal conductivity is irrelevant — what matters is temperature resistance and release performance.
A：Yes, our technical team is available for application consultation. We can review your process parameters (temperature profile, pressure, chemistry, cycle count), analyze your surface and geometry, and recommend the optimal film grade, thickness, and surface treatment. We also assist with adhesion testing protocols and can collaborate on custom development projects.
A：Sample requests can be made through our website, by email, or through your regional sales representative. We provide sample sets (typically A4 or A3 size sheets, or short roll lengths) for standard grades free of charge. For custom specifications, a small sample production fee may apply. Samples are typically dispatched within 3–5 business days.
A：We accept T/T (bank transfer), L/C, and for established customers, net payment terms. Shipping options include express courier (DHL/FedEx for samples and small orders), sea freight (FCL/LCL for large orders), and air freight for time-sensitive shipments. Incoterms FOB, CIF, and DDP are available. Freight costs vary — please request a quotation with your specific order volume and destination.
A：PTFE films are extensively used in fuel cell and electrolyzer manufacturing: as backing substrates during MEA (Membrane Electrode Assembly) hot press lamination, as release sheets for CCM (Catalyst Coated Membrane) transfer printing, and as gasket materials. PTFE's chemical resistance to both hydrogen and oxidizing environments makes it uniquely suited for these electrochemical applications.
A：PTFE offers lower dielectric constant (2.1 vs. PEEK's 3.2–3.3), better chemical resistance, and superior release properties — ideal for electrical insulation where adhesion to surrounding materials must be avoided. PEEK provides higher tensile strength (60 MPa vs. PTFE's ~27–30 MPa), better creep resistance under mechanical load, and can be used as a structural insulating component. Selection depends on whether mechanical or electrical properties dominate.
A：PTFE has excellent radiation resistance compared to most polymers. It can withstand gamma radiation doses up to 100 kGy (the standard medical sterilization dose is 25–50 kGy) without significant degradation in mechanical or chemical properties. This makes our PTFE films suitable for packaging and components in gamma-sterilized medical devices.
A：Our PTFE tapes are unaffected by high humidity in storage or use — PTFE's near-zero water absorption ensures no performance change in tropical climates. The silicone PSA is also moisture-stable. We recommend storing rolls in their original packaging away from direct sunlight. Shelf life exceeds 24 months under recommended conditions (15–35°C, <80% RH).
A：Yes, our products are produced in a quality management system certified to IATF 16949 and AS9100 standards. Aerospace-grade PTFE films can be supplied with full material certifications, traceability documentation, and test reports per AS9100 requirements.
A：PTFE has one of the lowest friction coefficients of any solid material (μ = 0.04–0.10, static and dynamic). This means our PTFE films function not only as release layers but also as low-friction bearing films, slide pads, and wear surfaces in mechanical assemblies. Applications include bridge expansion joints, architectural sliding joints, and machinery bearing surfaces.
A：Yes, our PTFE films (MR1/2 series in natural/translucent) and ETFE-based films offer high optical clarity — ETFE transmits over 90% of visible light. For applications requiring visual inspection through the release layer during processing (e.g., composite lay-up, adhesive bond inspection), our ETFE-EC film (white, slightly translucent) or thin PTFE films are recommended.
A：Our bare PTFE film is available in standard widths up to 1,220mm (MR1/2 series) and up to 1,270mm (VB-3 series). For applications requiring widths beyond these, we can explore custom production or joining of strips. The maximum width is determined by our casting line width. Contact our technical team for wider-format requirements.
A：Yes, PTFE tape is excellent for masking in surface treatment processes. It is resistant to the acids, alkalis, and plating bath chemicals used in anodizing (sulfuric, chromic, phosphoric acids), electroplating baths, and chemical etching processes. It leaves no adhesive residue and maintains its masking performance in both acidic and alkaline bath environments.
A：Our PTFE film has a dielectric strength exceeding 50kV/mm at 25μm thickness, and dielectric constant of 2.1 (stable across all frequencies and temperatures). Volume resistivity exceeds 10¹⁸ Ω·cm. These outstanding electrical properties make PTFE the preferred insulation material for high-frequency circuits, transformers, and high-voltage applications.
A：Our PTFE films can be fabricated into continuous belts for conveyor oven applications in electronics (reflow soldering, conformal coating cure), food processing, and industrial curing lines. Belt widths up to 1,220mm and any length can be supplied. Custom joining (seaming) methods are available. The belts can run at speeds of several meters per minute at temperatures up to 260°C.
A：PTFE has very low thermal shrinkage (<1% in both directions at 200°C), ensuring dimensional stability during high-temperature processing. ETFE-EC shows ≤5°C thermal shrinkage specification. Minimal shrinkage is critical in precision composite manufacturing where dimensional tolerances are tight. We provide shrinkage data across the operating temperature range upon request.
A：PTFE offers the highest continuous service temperature of all our films (260°C) and the lowest surface energy, making it the best release performance. PFA provides similar chemical resistance and slightly better flow in melt-processed forms. For release film applications, PTFE is generally preferred. PFA film excels in thermoforming applications where complex shapes are required.
A：Yes, our PTFE and ETFE release films are used in lithium-ion battery manufacturing: as release substrates during electrode slurry coating and drying, as separator films during calendering, and as peel-off layers for transfer coating processes. They are chemically resistant to battery electrolytes (NMP, DMF, ethylene carbonate) and stable at electrode drying temperatures (120–180°C).
A：PTFE is inherently hydrophobic with a water absorption rate near zero (<0.01%), making it unaffected by humidity or moisture exposure. Unlike polyimide or other high-temp films, PTFE does not absorb moisture that could vaporize during heating (causing blistering). This makes our PTFE films particularly reliable in tropical or humid manufacturing environments.
A：Our PTFE-based films comply with: FDA 21 CFR 177.1550 (PTFE resins for food contact), EU Regulation 10/2011 (food contact plastics), and are free from substances of concern under REACH and RoHS regulations. For pharmaceutical applications, materials comply with USP Class VI and ISO 10993 biocompatibility standards. Full regulatory documentation packages are available.
A：Absolutely — PTFE sheets are a staple in heat press and sublimation printing. They protect the heat platen from sublimation ink transfer, protect garments from direct heat contact, and prevent ghosting. Our PTFE films at 100–160μm thickness are the ideal range for this application. They can be used repeatedly across hundreds of heat press cycles.
A：Yes, PTFE release films are excellent release layers for silicone rubber molding. PTFE's low surface energy means even silicone (itself a release agent for many materials) does not adhere. This is crucial for RTV molding where the part would otherwise stick to silicone tooling. We recommend our HSM 22S or HM 32S grades for silicone molding applications.
A：Our PTFE tapes are available in standard widths ranging from 6mm to the full film width (up to 1,220mm for PTFE). Custom slit widths can be supplied in increments as small as 1mm, subject to minimum order quantities. Common narrow slit widths (12mm, 25mm, 50mm, 100mm) are typically in stock for fast delivery.
A：For optimal application: ensure the surface is clean, dry, and free of oils; apply at room temperature with moderate pressure; smooth out air bubbles. For removal: allow the substrate to cool to below 100°C before peeling; peel at a low angle (15–30°) against the direction of application. If residue occurs, clean with IPA solvent. Avoid removal at peak operating temperature.
A：Yes, our PTFE tapes are specifically suitable for powder coating masking applications. They withstand typical powder coating cure temperatures (160–220°C) without delaminating, burning, or leaving adhesive residue. They are easy to remove after cooling and leave clean, sharp masking lines. Used for protecting threads, bearings, and precision surfaces from powder coating overspray.
A：Our PTFE films have a very smooth surface (Ra <0.1μm for standard glossy grades). The film surface directly transfers its finish to the composite or molded part during curing — glossy PTFE produces glossy parts, textured PTFE produces matte or patterned surfaces. We can supply custom surface finishes (gloss, matte, micro-textured) depending on your aesthetic or functional requirements.
A：PTFE is biologically inert, non-toxic, and FDA-approved for medical use. Our PTFE films contain no plasticizers, fillers, or additives that could leach. They are used in medical device manufacturing as release layers in molding, as packaging films, and in catheter and implant production. ISO biocompatibility testing documentation is available upon request.
A：Yes, PTFE remains flexible and functional at cryogenic temperatures down to -200°C (liquid nitrogen temperature). Unlike most polymers that become brittle, PTFE retains its structural integrity and chemical resistance at cryogenic conditions. This makes our PTFE films suitable for LNG tank sealing, cryogenic valve packing, and aerospace applications involving liquid propellants.
A：The color differences reflect different backing film thicknesses and adhesive thicknesses: Orange HSM 22S (100μm = 50μm film + 50μm adhesive) offers maximum conformability. Gray HSM 22S (80μm = 50μm film + 30μm adhesive) is thinner with less adhesive. HM 32S (110μm) and HM 52S (160μm) use thicker film for longer service life. Choose based on conformability needs vs. durability requirements.
A：Our ETFE-based films can serve as vacuum bagging components due to their excellent gas barrier properties and heat resistance up to 165°C (ETFE-EC) or 260°C (PTFE). For standard epoxy prepreg curing (120–180°C), our films are compatible. For PEEK and high-performance thermoplastic composites requiring >200°C, the PTFE grade is recommended.
A：Our PTFE-based films resist virtually all solvents used in electronics: isopropyl alcohol (IPA), acetone, MEK, toluene, flux activators, and conformal coating solvents. PTFE's chemical resistance is among the highest of any polymer. Our ETFE-EC variant also offers good solvent resistance, with specific compatibility data available.
A：The silicone PSA on our PTFE tapes provides moderate-high initial tack, sufficient for secure positioning during assembly. Specific peel strength values are available per product grade. Adhesion to stainless steel is typically higher than to PTFE or ceramic surfaces. Elevated temperature reduces effective peel strength slightly — data at 25°C and 180°C available on request.
A：Reuse cycles depend heavily on operating temperature, pressure, and the surface being released from. Under typical press curing conditions (180°C, 5 bar), our PTFE films typically last 10–50 cycles. In lighter applications such as heat sealing jaws (160°C), service life can extend to hundreds of cycles. We recommend testing under your specific conditions for precise cycle count data.
A：Our PTFE and PET release tapes are widely used in PCB manufacturing: as masking tape during wave soldering , as a carrier film for SMT pick-and-place processes, and as a separator in stack-press lamination of multilayer PCBs. They withstand lead-free solder temperatures (260–280°C).
A：Yes, our PTFE release films are widely used in autoclave composite manufacturing. They function as peel-ply or release layer between the part and tooling/vacuum bag. The film releases cleanly after curing at temperatures up to 260°C and pressures up to 10 bar (typical autoclave conditions). It leaves no residue on carbon fiber or glass fiber parts.
A：Key industries include: electronics manufacturing (wave soldering, conformal coating masking), composite manufacturing (autoclave and press curing), food processing equipment (non-stick conveyor belts and baking molds), packaging (heat sealing jaws), and aerospace (pre-preg lay-up and vacuum bagging). In all cases, the film must survive process temperatures while releasing cleanly without contaminating the product.
A：Our PTFE tapes use silicone pressure-sensitive adhesive (PSA), which maintains adhesion and release properties across the full temperature range (-70°C to +260°C). Our ETFE-EC tape uses acrylic PSA, which is preferred for moderate temperature applications (up to 165°C) where longer-term bonding strength is more important than ultra-high-temp performance.
A：We offer four main PTFE tape configurations: HSM 22S (100μm or 80μm), HM 32S (110μm), and HM 52S (160μm). Thinner films (80–100μm) are used where conformability and close contact are needed; thicker films (110–160μm) offer longer service life in repeated-use press operations. We recommend discussing your cycle counts and pressure parameters.
A：Our PTFE-based release films withstand continuous operation at +260°C (500°F) and can tolerate short-term peaks up to +280°C. ETFE-EC variants operate continuously at -150°C to +165°C. PET-based variants have a maximum of 204°C. The choice depends on your process requirements.
A：A high-temperature release film is a specialty film coated with release agents (typically silicone or fluoropolymer) that prevents adhesion at elevated temperatures. Our product line uses PTFE (Teflon) film as the primary substrate, offering release properties from -70°C to +260°C. We also offer ETFE-EC variants with acrylic adhesive for specific bonding applications.
A：ETFE has higher tensile strength (48MPa vs. FEP's ~24MPa) and better abrasion resistance, making it preferred for wire and cable jacketing in aerospace and military applications where mechanical durability is critical. FEP offers slightly better chemical resistance and lower friction. ETFE is preferred where mechanical toughness matters most.
A：Standard ETFE is an excellent electrical insulator (surface resistivity >10¹⁶ Ω/sq), which can present ESD risks in electronics manufacturing. We offer antistatic-treated or carbon-loaded ETFE grades with surface resistivity in the 10⁶–10⁹ Ω/sq range, suitable for ESD-sensitive assembly lines and component packaging.
A：ETFE demonstrates excellent resistance to hydrofluoric acid (HF), sulfuric acid, nitric acid, and most organic solvents — substances that attack many other plastics and metals. It is widely used in semiconductor wet processing equipment, chemical handling lines, and cleanroom applications. Chemical compatibility charts are available.
A：ETFE has a dielectric constant of approximately 2.6–2.8 at 1MHz and remains stable across a wide frequency range. This low, stable dielectric constant makes ETFE suitable for high-frequency microwave PCB substrates, antenna insulation layers, and radar equipment. We can provide dielectric property data sheets for design engineers.
A：ETFE is available in roll format as standard. Roll lengths depend on thickness and width — typically 100–500 linear meters per roll, with each roll weighing approximately 10–15kg. Sheet cutting is available for custom dimensions. We can discuss specific roll configurations based on your processing needs.
A：ETFE is gaining attention in flexible electronics due to its electrical insulation, flexibility, and chemical resistance. It is used as a substrate for flexible circuits and piezoelectric sensors, and as encapsulation for wearable electronics. Its biocompatibility also makes it suitable for medical wearables. Custom thin gauges (down to 12μm) are available.
A：Single-layer ETFE has a U-value similar to single-pane glass (~5.7 W/m²K). However, multi-layer ETFE cushion systems with trapped air layers achieve U-values of 1.5–2.0 W/m²K, comparable to double-pane low-E glass. Four-layer cushions can achieve U-values below 1.0 W/m²K, offering excellent thermal performance.
A：Our ETFE film maintains its optical and mechanical properties for over 25 years of outdoor exposure. We conduct accelerated weathering tests equivalent to 30+ years using xenon arc chambers. ETFE does not yellow, crack, or delaminate under prolonged UV exposure. Long-term performance data is available upon request.
A：Yes, we offer ETFE with custom perforation patterns. Perforated ETFE is used in acoustic panels (sound absorption while maintaining transparency), ventilated façades, air distribution systems in greenhouses, and filtration media. Hole size, pitch, and pattern can be customized to meet airflow or acoustic requirements.
A：Every production run undergoes online defect detection using optical inspection systems, thickness measurement with in-line gauges, and melt flow index testing. Pre-shipment checks include tensile strength, elongation, transmittance, and surface energy tests. We maintain full batch traceability and provide CoA (Certificate of Analysis) with every shipment.
A：Yes, ETFE is an ideal substrate for BIPV applications. It can receive screen-printed, inkjet-printed, or sputtered photovoltaic cell patterns and conductive inks. Its transparency allows for semi-transparent BIPV panels that double as architectural glazing. We can supply treated ETFE ready for PV processing.
A：ETFE is inherently flame-retardant without additives — it has a limiting oxygen index (LOI) above 30%, meaning it does not sustain combustion in normal air. Upon ignition, it self-extinguishes and does not drip burning material. It meets UL94 V-0 rating and satisfies European fire class B-s1,d0 requirements for many building applications.
A：Our ETFE film holds UL certification and passes HF (halogen-free flame) and SGS testing. Products are RoHS compliant and meet REACH SVHC substance requirements. Additional certifications such as IATF 16949 (automotive) and AS9100 (aerospace) are available for specific product lines.
A：Our ETFE film is produced without plasticizers or additives, making it compliant with FDA 21 CFR regulations for food contact and suitable for pharmaceutical applications. It has excellent chemical inertness and will not leach compounds into food or drug products. Documentation for compliance is available upon request.
A：Yes, ETFE can be laminated with metals (aluminum, copper), textiles, foams, and other films. Surface treatment (plasma or chemical etching) is required first to enhance adhesion. We supply ETFE pre-treated and ready for lamination, and can collaborate on composite development projects.
A：Minimum order quantities vary by specification. Standard products (common thicknesses and widths) typically have an MOQ of 100kg. Custom specifications may require higher minimums. Standard lead time is 2–4 weeks; custom orders may require 4–8 weeks. Please contact our sales team for specific quotations.
A：ETFE is fully recyclable — it can be melted down and reprocessed into new film. Its production energy is significantly lower than glass per unit area (ETFE weighs ~350g/m² vs. 25kg/m² for glass). The longevity of ETFE further reduces lifecycle environmental impact. We are aligned with circular economy principles.
A：ETFE's resistance to radiation, extreme temperature cycling (-70°C to +150°C), and vacuum conditions make it highly suitable for aerospace wiring insulation, flexible solar array substrates, and thermal blankets. It holds AS9100 certification eligibility and passes outgassing tests per ASTM E595 standard.
A：ETFE has an extremely low surface energy (~31 mN/m), which causes water to bead and roll off, carrying dust particles away. Rain is typically sufficient to keep ETFE surfaces clean. In heavily polluted urban environments, occasional washing with water is recommended. No chemical cleaners are needed.
A：Our ETFE has a tensile strength of 48 MPa and elongation at break of 300%. For wind loading in architectural applications, ETFE cushion systems are designed to be pre-stressed — the pneumatic inflation pressure is adjusted so the film carries loads through tension rather than bending. Engineering support for load calculations is available.
A：ETFE is an excellent greenhouse material. It outperforms standard PE film in several ways: lifespan exceeds 20 years (vs. 1–3 years for PE), it maintains transmittance without yellowing, is chemically resistant to pesticides and fertilizers, and is fully recyclable. While the upfront cost is higher, the long-term ROI is significantly superior.
A：We offer ETFE in transparent, white, frosted (matte), red, blue, and with dot-pattern (frit) printing. Custom colors and printed patterns — including branding, gradients, and decorative motifs — are available for architectural and design applications. Minimum order quantities apply for custom prints.
A：ETFE offers higher light transmittance (>90% vs. ~88% for PVDF), greater flexibility, and superior weathering resistance over 25+ years. PVDF is more cost-effective and easier to thermoform. For high-efficiency flexible modules, ETFE is preferred; for conventional rigid panels requiring easy processing, PVDF is often chosen.
A：Our ETFE film meets key PV industry requirements including IEC 61215, IEC 61730, and UL certifications. It passes PCT accelerated aging tests and damp-heat tests (85°C/85% RH for 1,000 hours). ETFE is widely used as front-sheet material for flexible and bifacial solar modules.
A：We offer plasma treatment and chemical etching (sodium etching) for ETFE. Plasma treatment is recommended for bonding, printing, or lamination applications. Chemical etching creates a micro-rough surface that significantly enhances adhesion — ideal for structural composites or when applying pressure-sensitive adhesives.
A：Yes, ETFE is fully heat-weldable using standard hot-air welding or wedge-welding machines. No special solvents are required. Our technical team can provide welding parameter guidelines (temperature range 250–280°C, speed settings) and on-request training support for fabricators.
A：ETFE retains excellent flexibility and mechanical strength at temperatures as low as -70°C, making it suitable for Arctic and sub-Arctic climates. Its elongation at break remains at 300%, preventing cracking. The material does not become brittle in freezing conditions, unlike many alternatives.
A：Our ETFE film achieves over 92% light transmittance (HP/AG grades). ETFE naturally blocks short-wave UV below 200nm; mid-range UV (280–380nm) is partly transmitted. For applications requiring controlled UV filtering — such as greenhouses or museums — we can add UV-blocking coatings or additives.
A：Our standard ETFE film ranges from 12µm to 500µm in thickness. Standard width reaches 1,600mm, with custom widths up to 2,100mm available. We support full customization of thickness, width, length, and color to match your project specifications.
A：ETFE (Ethylene Tetrafluoroethylene) is a fluoropolymer film known for its exceptional transparency (>92%), light weight (1% of glass), and tensile strength. Unlike glass, ETFE can be formed into pneumatic cushion structures, is self-cleaning, and has a lifespan exceeding 25 years. Compared to polycarbonate, it offers superior UV resistance and does not yellow over time.
A：In specific release and technical applications, our ETFE MR (Release Grade) film is 20% lighter per unit area than FEP film, which can reduce the overall structural load of your project.
A：Thanks to its low coefficient of friction and non-stick properties, the film exhibits a "Lotus Effect". Dust and dirt do not easily adhere to the surface and are typically washed away by natural rainfall.
A：Yes. Our ETFE AG (Architectural/Agricultural Grade) series comes in transparent, matte, white, and blue. We also offer functional variants such as UV-blocking or Infrared-blocking versions to optimize the growing environment.
A：Yes. We provide specialized surface treatments, including plasma treatment and chemical etching, to create bondable surfaces for complex composite applications or frame attachments.
A：We offer a versatile range of thicknesses from 12µm to 500µm. While our standard maximum width is 2100mm, we can slit the film to any width based on specific customer requirements.
A：No. Our ETFE film has an extremely low water absorption rate of <0.03% and is chemically inert to most chemicals and solvents used in agricultural processes.
A：Our film is engineered for durability. It has a tensile strength of 48 MPa and a high elongation at break of 300%. This flexibility allows it to absorb impacts from hail or withstand high wind loads without tearing.
