FEP for Cable & Wire — Low-Smoke, Halogen-Free Insulation Resin
FEP (fluorinated ethylene propylene) is a key wire-and-cable fluoropolymer — low-smoke, halogen-free and flame-resistant, with a wide MFR range for both extrusion and injection molding.
Peflon FEP for Cable & Wire
Peflon’s FEP cable resins offer a wide range of MFRs (2.0 to 32 g/10 min) and suit both extrusion and injection molding. Our fluorinated ethylene propylene (FEP, CAS 25067-11-2) wire resins are low-smoke, halogen-free and environmentally safe.
Its wire-grade FEP resin makes flexible cables with high melt strength, stable processing temperatures and excellent resistance to chemicals and solvents, with operating temperatures from −80 °C to 200 °C (−112 °F to 392 °F). See general FEP property data. OEM services are available for customized needs.
Why Peflon FEP Wire Resin
Seven reasons buyers specify Peflon FEP for demanding wire and cable — from regulatory compliance to flame resistance, flexibility and processing ease.
PFOA-Free, PFAS-Free
Peflon abandons traditional perfluorooctanoate salts and uses advanced production technology — free of PFOA and PFAS, compliant with EU REACH.
Halogen-Free
Passes REACH testing and is halogen-free — free of chlorine (Cl) and bromine (Br) — compliant with EU standards.
High-Temperature Resistant
Peflon FEP cable jacket supports continuous service from −80 °C to 200 °C (392 °F).
Widely Used in Various Cables
Covers a wide range of wire sizes and wall thicknesses — coaxial, tray, down-hole, LAN, high-speed data, heating, plenum and control cables.
Unique Flame Resistance
Excellent fire resistance — withstands temperatures above 800 °C before burning, smoking or decomposing.
Extreme Flexibility
High flex performance — wires can continuously flex up to and beyond 10 million cycles.
Easy to Process
With a melting point of 260 ± 5 °C, Peflon FEP has high melt strength and stable processing temperatures, making it easy to melt-extrude.
FEP for Cable & Wire — Frequently Asked Questions
What MFR range does Peflon FEP for wire & cable cover?
Peflon offers FEP cable resins across a wide MFR window of 2.0 to 32 g/10 min, so you can match melt flow to line speed and wall thickness for both extrusion and injection molding.
Is FEP suitable for plenum (CMP) cable?
Yes. FEP is a primary plenum-rated insulation material thanks to its low smoke generation, flame resistance and low, stable dielectric constant — widely used in CMP, coaxial and high-speed data cable.
What temperature rating does FEP cable insulation have?
Peflon FEP cable jacketing runs continuously from −80 °C to 200 °C (−112 °F to 392 °F) and resists fire above 800 °C before decomposing, with a melting point of 260 ± 5 °C.
Is Peflon FEP for wire halogen-free and PFOA-free?
Yes — it is halogen-free (no chlorine or bromine), low-smoke and produced without PFOA or PFAS, passing REACH testing and compliant with EU standards.
Why is FEP good for high-speed data and coaxial cable?
FEP has a low, stable dielectric constant (~2.1) and low dissipation factor, which preserve signal integrity at high frequencies — combined with flame resistance, that makes it ideal for coaxial, LAN and high-speed data cable.
Which cable types use Peflon FEP resin?
Coaxial, tray, down-hole, LAN, high-speed data, heating, plenum and control cables — across a wide range of wire sizes and wall thicknesses, in both jacketing and primary insulation.
