Copolymers of tetrafluoroethylene and a perfluorinated vinyl ether, Fluon® PFA Resins can be used over a wide range of temperatures from extremely low to high (-200 °C to 260 °C) without losing excellent chemical, electrical, mechanical and surface properties. PFA resins retain many inherent characteristics and similar properties of PTFE, but can be processed using conventional thermoplastic techniques such as extrusion molding, injection molding, blow molding and electrostatic powder coating. With an oxygen index of 95% or better, these noncombustible resins can be used in various fields. Offering outstanding weatherability (no reduction or deterioration by direct sunlight, wind, rain and exhaust gas), characteristics do not change when exposed to the outdoors for a long period of time. Fluon® PFA resin compounds are also available.
