Hyflon® 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® 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® M640 is a low melt flow rate multi-purpose resin designed for pipe, cable, and stock shapes extrusion, injection, compression, and transfer molding. Hyflon® M640 has obtained UL758 recognition for continuous use at 250°C (482°F) and is an ASTM D3307 - Type VII resin.
