FEP Copolymer Filament is a fluorinated ethylene propylene copolymer, in filament form. FEP copolymer offers excellent chemical resistance and electrical insulation properties. With 35 variations, Goodfellow's range of FEP copolymer filaments is suitable for a wide array of scientific and industrial applications such as wire and cable insulation, linings for pipes and tanks, and protective coatings. The copolymer's high melting point also makes FEP filament useful in high temperature environments.
