PFA

PFA (perfluoroalkoxy) is a high-performance fluoropolymer thermoplastic that combines the chemical inertness and temperature resistance of PTFE with improved processability and mechanical toughness. It is widely used in chemical processing, semiconductor manufacturing, and fluid handling applications where exposure to aggressive chemicals, elevated temperatures, and thermal cycling demands a material that can be injection molded or extruded into complex shapes while maintaining dimensional stability. Engineers select PFA over PTFE when fabricated parts are required (rather than machined stock) or when superior creep resistance and flexibility are needed in chemically harsh environments.
