Teflon™ FEP

Teflon™ FEP is a fluorinated ethylene propylene resin that meets the ASTM standard specification for FEP—Fluorocarbon Molding and Extrusion Materials under ASTM D-2116-02. It is used for a wide range of applications, from insulation to jacketing, in various types of LAN and coaxial cabling.

Our family of Teflon™ FEP resins are available as pellets or as stabilized aqueous dispersions and offer an excellent combination of properties for wire and cable applications, including:

  • low flammability
  • exceptional dielectric properties
  • heat resistance
  • flexibility
  • low coefficient of friction
  • nonstick characteristics
  • negligible moisture absorption
  • chemical inertness
  • performance at temperature extremes (-200°C to 200°C) 
  • weather resistance

Family of Teflon™ FEP Resins for Wire and Cable Applications

Teflon™ FEP 9494
Teflon™ FEP 9494 is a melt-processible fluoroplastic resin specifically designed for high-speed extrusion of thin coatings on small-gauge wires for twisted-pair constructions.

Teflon™  FEP 100
Teflon™ FEP 100 is suitable for extrusion as a primary coating onto most gauge wires AWG 12 and smaller. Teflon™  FEP 100 resin provides the electrical and mechanical properties needed for many low-voltage applications for twisted-pair constructions for limited jacketing applications.

Teflon™  FEP CJ95
Teflon™ FEP CJ95 should be applied where experience has shown that a higher degree of stress-crack resistance is or might be required. Typical applications include most wire sizes larger than AWG 12 and smaller wire sizes where high current loads are carried or where thermal cycling is expected. Teflon™ FEP CJ95 should be considered for jackets over wire braid constructions such as coaxial cables and heater cable jackets. Other applications include insulation or jacketing over non-round or flat conductors, power or lighting circuits, motors or appliances where frequent temperature cycling can occur.

Teflon™ FEP CJ99
Teflon™ FEP CJ99 is a melt-processible fluoroplastic resin specifically designed for applications that demand a high degree of stress-crack resistance. This one resin can replace a whole range of resins in the MFR 5 to 10 g/10 min range, as it can be applied on a wide range of wire sizes, in a wide range of wall thicknesses, and is suitable as a jacketing resin as well.

Teflon™  FEP 106
Teflon™ FEP 106 is a high productivity grade of Teflon™ FEP. At processing temperatures, it shows low viscosity and a high critical shear rate. Compared to the general-purpose grade Teflon™ 100N, it can be extruded at faster rates and higher line speeds. Final products show comparable physical properties although the stress-crack resistance will be marginally inferior than Teflon™ 100N. Typical applications for this grade include automotive, appliance, and heating cable primaries.
