| Hyflon® PFA is a unique family of semi-crystalline, melt processable perfluoropolymers which combine excellent mechanical characteristics to unique properties such as chemical inertness, heat resistance, inherent flame resistance, low surface energy, and exceptional dielectric properties. Hyflon® PFA resins have been designed to retain their properties over a wide range of temperatures from cryogenic to 250-260°C (482-500°F) and are the material of choice in applications such as linings in the Chemical Process Industry, specialty cables, semiconductor industry, aerospace, and other challenging industries. Hyflon® PFA P450 is a medium molecular weight, high melt flow rate multi purpose resin designed for cable extrusion and injection molding. Hyflon® PFA P450 has obtained UL758 recognition for continuous use at 260°C (500°F) and is an ASTM D3307 – Type I resin.&& |
