Perfluorinated ethylene-propylene (FEP) is the copolymer of tetrafluoroethylene



(TFE) and hexafluoropropylene (HFP) with excellent thermo-stability and chemical



inertness, outstanding electrical insulation and very low friction coefficient. The



thermoplastic process techniques can be used to fabricate useful products from



FEP.
