FEP molding (lining) grade
Fluorinated 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.
