fluorinated ethylene-propylene copolymer

polymer

Fluorinated ethylene-propylene copolymer (FEP) is a fluoropolymer thermoplastic combining ethylene and propylene monomers with fluorine substitution, offering exceptional chemical resistance and non-stick properties. It is widely used in chemical processing, electrical insulation, non-stick coatings, and pharmaceutical manufacturing where exposure to aggressive solvents, oils, and corrosive media demands superior resistance compared to standard plastics. Engineers select FEP over unfluorinated polymers when non-reactivity, low friction, and thermal stability in demanding chemical environments are critical; it is also preferred over perfluorinated polymers like PTFE where slightly better processability and lower cost are acceptable trade-offs.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
