Teflon and FEP Wire and Cables

Teflon and FEP Wire and Cables

Teflon (PTFE) and FEP (FluorEthylenePropylene) are very similar in composition of fluoropolymers PTFE (PolyTetraFluoroEthylene) and PFA (PerFluoroAlkoxy polymer resin). FEP and PFA both share PTFE’s useful properties of low friction and non-reactivity but are more easily formable.



FEP is softer than PTFE and melts at 260°C; it is highly transparent and resistant to sunlight. Thermally, FEP stands out from PTFE and PFA by having a melting point of 260°C, around forty degrees lower than PFA and lower again than PTFE.


Thus FEP and Teflon are ideal insulation materials for wire and cables where the cable is exposed to environment:


  • Resistant to Fire
  • Chemicals, Acids
  • Sunlight
  • Moisture
  • Corona
  • High Voltage
  • Temperature range -65°C to 220°C
  • Applicable standards JSS 51034 and MIL 16878-D

    Electrically, PTFE, FEP and PFA have identical dielectric constants, but FEP’s dielectric strength is only surpassed by PFA. We are offering single core wires and multi-core cables in user specific design.
