What is Teflon FEP?
Peflon FEP is a copolymer of hexafluoropropylene and tetrafluoroethylene, known for its chemical resistance, non-stick properties, and high transparency. It differs from polytetrafluoroethylene (PTFE), which is typically used for chemical inertness, flexibility, and resistance to temperature.
If you’re evaluating a second source for an existing FEP grade, share your current part or datasheet target — we’ll shortlist an equivalent Peflon grade with COA/SDS for faster internal approval.
With Peflon, you source FEP material in practical forms such as resin pellets and application grades (CAS 25067-11-2), supported by COA/SDS for faster internal approval. See independent FEP material properties for baseline data.

How Processors Convert Peflon FEP
Peflon supplies FEP resin, powder and dispersion in grades matched to how you’ll process them — melt extrusion, injection or compression molding, spray/powder coating, and dispersion impregnation each call for a different form and MFR range. Extrusion and injection grades (PF-302–PF-311) cover tubing, film, cable insulation and precision molded parts; PF-301 is formulated specifically for compression molding; PF-3D03 dispersion supports coating and glass-fabric impregnation, while PF-3P51 and PF-3MP05 powder grades suit electrostatic and anti-corrosion coating. Confirming your process before ordering — not just your application — narrows grade selection to a shortlist your team can validate against TDS data.
Extrusion
Processors melt-extrude Peflon FEP pellets at approximately 330–420°C into film, tube, rod and wire & cable insulation.
Spray & Powder Coating
Processors apply Peflon FEP dispersion or electrostatic powder, fusing at approximately 385–400°C into a nonporous coating rated to 200°C continuous use.
Injection Molding

FEP Material — Frequently Asked Questions
These are the questions FEP buyers ask most before specifying a grade — covering chemical compatibility, service temperature, processing method, wire & cable use and PFAS/FDA compliance documentation.
How is FEP different from PTFE?
FEP (fluorinated ethylene propylene) shares PTFE’s chemical inertness and non-stick surface but is fully melt-processable. Unlike PTFE, FEP can be extruded, injection-molded and heat-sealed on conventional thermoplastic equipment, trading a slightly lower continuous-service temperature (200 °C vs 260 °C) for far easier processing and optical clarity.
Which processing methods does Peflon FEP support?
Our FEP resins cover the full melt-processing range — melt extrusion for tube, wire & cable and film, injection and blow molding for parts, and rotolining for equipment. Grades are supplied by melt-flow rate (MFR) so you can match the resin to your line speed and wall thickness; dispersion and micropowder grades are available for coating and additive use.
What is the continuous service temperature of FEP?
Peflon FEP has a maximum continuous service temperature of about 200 °C (392 °F) and retains flexibility and dielectric performance from cryogenic temperatures upward, with a melting point near 260 °C. It stays chemically resistant to virtually all acids, bases and solvents across that range.
Is FEP suitable for wire & cable insulation?
Yes. FEP is a primary insulation material for plenum-rated (CMP) cable, coaxial and hook-up wire thanks to its low, stable dielectric constant (~2.1), low dissipation factor, flame resistance and low smoke generation. Peflon offers dedicated high-speed extrusion grades for wire & cable — see our FEP for cable & wire grades.
Is Peflon FEP FDA-compliant for food and pharmaceutical contact?
Yes. Our virgin FEP resins are PFOA-free and formulated to meet FDA 21 CFR 177.1550 for repeated food-contact use; REACH, RoHS and SVHC statements plus per-batch COA are available on request. This makes FEP suitable for food-processing tubing, pharmaceutical fluid transfer and medical devices.
Is FEP considered a PFAS?
Yes — FEP is a fluoropolymer, which falls within the broad regulatory definition of PFAS (per- and polyfluoroalkyl substances) used by the EPA and OECD. See our PFAS facts page for how fluoropolymers differ from other PFAS subclasses and what that means for compliance documentation.
Does Peflon supply FEP for coating applications?
Yes. Peflon supplies FEP as an aqueous dispersion or electrostatic powder for spray and powder coating, fused at approximately 385–400°C to form a nonporous film with a maximum continuous-use temperature of 200°C.
Is Peflon a reliable second-source alternative to Daikin, Chemours or DuPont FEP?
Yes. Peflon supplies documented FEP grades with full TDS/SDS traceability so buyers can qualify us as a second source alongside an existing supplier, without re-engineering their specification.
Which FEP grade should I choose for injection or compression molding?
Grade selection depends on melt-flow rate and wall thickness. See our molding-grade FEP options or contact our technical team for a grade match.
Does Peflon supply colored FEP or FEP masterbatch?
Yes. Peflon supplies FEP masterbatch — color concentrate pre-dispersed in an FEP carrier resin matched to your grade — for cable jacketing, tubing and molded-part color coding.

What is PTFE
Need PTFE’s ~260°C ceiling instead? Peflon supplies both — compare grades before you switch base materials.
PCTFE
Need near-zero permeation or cryogenic sealing? Peflon also supplies PCTFE, the higher-barrier fluoropolymer alternative to FEP.
Technical Support of FEP Material
Specifying FEP wrong is expensive to fix after tooling is cut. Before you lock in a grade or a new supplier, these three guides cover the decisions buyers ask about most: wire insulation grades, tube manufacturing tolerances, and supplier qualification.
How to Choose the Suitable FEP Resin in the Wire Industry
Picking the wrong MFR grade for your line speed is the most common wire-insulation mistake — match grade to wall thickness and speed before you order.
How to Choose the Right FEP Resin Grade for Tube Manufacturing
Tube wall tolerance and burst pressure depend on grade selection as much as machine settings — see how to match FEP grade to your tube spec.
