SolvaySpecialty Polymers Hyflon® PFA P450 Perfluoroalkoxy (PFA)

PFA

Solvay Specialty Polymers

产品说明：

Hyflon® PFA is a unique family of semi-crystalline, meltprocessable perfluoropolymers which combine excellent mechanicalcharacteristics to unique properties such as chemical inertness,heat resistance, inherent flame resistance, low surface energy, andexceptional dielectric properties. Hyflon® PFA resins have beendesigned to retain their properties over a wide range oftemperatures from cryogenic to 250-260°C (482-500°F) and are thematerial of choice in applications such as linings in the ChemicalProcess Industry, specialty cables, semiconductor industry,aerospace, and other challenging industries. Hyflon® PFA P450 is amedium molecular weight, high melt flow rate multi purpose resindesigned for cable extrusion and injection molding. Hyflon® PFAP450 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。
