FEP for Cable & Wire — Low-Smoke, Low-Halogen Insulation Resin
FEP (fluorinated ethylene propylene) is a key wire-and-cable fluoropolymer — low-smoke, low-halogen (Cl/Br) and flame-resistant, with a wide MFR range for both extrusion and injection molding.
- Five wire-grade FEP pellets, MFR 2.0–20 g/10 min, matched to line speed and wall thickness
- Cross-reference support against Teflon™ FEP grades — no spec re-engineering required
- KKDIK / REACH / FDA documented — trial samples available before you commit
케이블 & 전선용 Peflon FEP
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, low-halogen (Cl/Br) and produced without PFOA or PFAS. Peflon FEP grades used in plenum-rated communications cable are formulated to support the fire and smoke performance required by UL 444, the standard for communications cables referenced by NEC Article 800 CMP ratings — confirm compliance with your cable manufacturer’s own UL listing.
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). These five grades share the same base resin as Peflon’s broader 10-grade FEP catalog — if your process needs a coating-grade dispersion or powder instead, see the full range there.

Cable Types Using Peflon FEP Resin
Peflon’s FEP wire resins are extruded by processors into insulation and jacketing across a wide range of cable constructions — from hookup wire to high-temperature spark ignition cable.
Hookup & Control Wire
Processors extrude Peflon FEP onto hookup and control wire conductors where chemical resistance and a wide service-temperature range matter more than bulk insulation cost.
High-Temperature & Spark Ignition Wire
Processors specify Peflon FEP for spark-plug and ignition wire insulation where continuous service above 150°C and dielectric stability under vibration are required.
Shielded & Multi-Conductor Data Cable
Processors extrude thin-wall FEP insulation (PF-305) onto individually shielded conductors for high-speed data and LAN cable, where low, stable dielectric constant preserves signal integrity.
Plenum (CMP) & Low-Smoke Cable
Processors building CMP-rated communications cable specify FEP for its low smoke generation and flame resistance above 800°C, supporting the fire performance tested under UL 444.
How Processors Extrude Peflon FEP Onto Wire & Cable
Processors extrude Peflon FEP pellets onto bare or tinned copper conductor as primary insulation, or over a cabled core as an outer jacket — melt strength and stable processing temperature keep wall thickness consistent at line speed.
Primary Insulation Extrusion
Processors melt-extrude FEP directly onto bare or tinned copper conductor on wire lines, using MFR and melt strength to hold wall thickness at line speed.
Jacket Extrusion Over Cabled Core
Processors extrude a higher-MFR FEP jacket over a cabled, shielded core for multi-conductor and data cable constructions.
Foam-Skin Extrusion for High-Speed Data
Processors use a foamed FEP core with a solid skin to lower dielectric constant further for high-speed data cable — see Peflon’s foamed FEP resin guide for the process.

Peflon FEP 와이어 수지를 선택해야 하는 이유
Cable and wire manufacturers qualifying a new FEP resin source weigh regulatory documentation, MFR consistency and flame/smoke performance as heavily as price.
PFOA-Free, PFAS-Free & Low-Halogen
Peflon abandons traditional perfluorooctanoate salts and uses advanced production technology — free of PFOA and PFAS, compliant with EU REACH. Peflon FEP is also low-halogen (Cl/Br), per IEC 61249-2-21 — note that as a fluoropolymer, FEP inherently contains fluorine, which this standard does not restrict.
- REACH-compliant, PFOA/PFAS-free production
- Low-halogen (Cl/Br) per IEC 61249-2-21
Flame Resistance & Signal Integrity
Peflon FEP withstands temperatures above 800°C before burning, smoking or decomposing, supporting plenum-rated (CMP) constructions under UL 444 — while its low, stable dielectric constant (~2.1) preserves signal integrity in coaxial, LAN and high-speed data cable.
- Low smoke generation above 800°C
- Stable dielectric constant across frequency
Extreme Flexibility, Wide MFR Range
High flex performance — wires can continuously flex up to and beyond 10 million cycles. Five grades span MFR 2.1–20 g/10 min, matched to your line speed and wall thickness rather than a one-size-fits-all resin.
- 10M+ flex cycles, grade-dependent
- Grade cross-reference support against your current spec
Easy to Process, Documented Second Source
With a melting point of 260 ± 5°C, Peflon FEP has high melt strength and stable processing temperatures, making it easy to melt-extrude. Qualify Peflon as a documented second source alongside Daikin, Chemours or AGC — trial samples available before you commit.
- Stable processing window for consistent wall thickness
- Trial samples shipped with matching TDS
케이블 & 전선용 FEP — 자주 묻는 질문
전선 & 케이블용 Peflon FEP는 어떤 MFR 범위를 제공합니까?
Peflon은 2.0~32g/10min에 이르는 넓은 MFR 범위의 FEP 케이블용 수지를 제공하여, 압출 및 사출 성형 모두에서 용융 유동성을 라인 속도와 벽 두께에 맞출 수 있도록 합니다.
FEP는 플레넘(CMP) 케이블에 적합합니까?
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, tested against UL 444.
FEP 케이블 절연재의 내열 등급은 어떻게 됩니까?
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 low-halogen and PFOA-free?
Yes — it is low-halogen (Cl/Br, per IEC 61249-2-21), low-smoke and produced without PFOA or PFAS, passing REACH testing and compliant with EU standards. As a fluoropolymer, FEP inherently contains fluorine, which this standard does not restrict.
FEP가 고속 데이터 케이블 및 동축 케이블에 적합한 이유는 무엇입니까?
FEP는 낮고 안정적인 유전율(~2.1)과 낮은 유전손실계수를 가지고 있어 고주파에서도 신호 무결성을 유지하며, 난연성과 결합되어 동축, LAN 및 고속 데이터 케이블에 이상적입니다.
어떤 케이블 종류에 Peflon FEP 수지가 사용됩니까?
동축, 트레이, 다운홀, LAN, 고속 데이터, 히팅, 플레넘 및 제어 케이블 — 다양한 전선 규격과 벽 두께에 걸쳐 재킷재 및 1차 절연재 모두에 사용됩니다.
