FEP

Perfluorinated ethylene-propylene (FEP) for wire and cable is the copolymer of



tetrafluorothylene (TFE) and hexafluoropropylene (HFP) with excellent thermo-



stability, outstanding chemical inertness, low friction coefficient, distinctive air ag-



ing resistance, vapor penetrating resistance, non-inflammability and superior



electrical insulation. It is nearly stabilized in rather wide ranges of temperature and



frequency. And it can be widely used as wire and cable in the field of aircraft,



spacecraft, communication, computer, electricity instrument, high buildings and



high temperature up to 200°C for a long time, etc, due to its excellent interruption



& shielding resistance to communication signals. The thermoplastic process



techniques can be used to fabricate useful products from FEP.
