PFA
Solvay Specialty Polymers
产品说明:
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.

成型性能 1.结晶料,吸湿小。可采用通常得热塑性塑料得加工方法加工成制品。
3、流动性差,极易分解,分解时产生腐蚀气体。宜严格控制成型温度不要超过475度,模具应加热至150-200度,浇注系统对料流阻力应小。
4、半透明粒料,注塑、挤出成型。成型温度350-400度,475度以上容易引起变色或发生气泡。并注意脱模会较困难。
5、因熔融的材料对金属有腐蚀作用,长期生产,模具需要电镀铬处理。
PFA FEP PTFE 的化学性能相似,但FEP只能在200度以下使用,PTFE不能注塑。
