PPS BZ-A5

Alloy polyphenylene sulfide(PPS)

Product features

This kind of product is one of the high performance glass fiber reinforced polyphenylene sulfide(PPS) alloy series products manufactured by our company. It is made by adding PA66, glass fiber and related additives through twin-screw extruder on the basis of PPS resin. By adding PA66, the brittleness of PPS was improved, and the roughness of PPS was increased. Meanwhile, the strength also increases greatly. This kind of product has good mechanical properties, high rigidity, high toughness, high creep resistance, high temperature resistance, chemical corrosion resistance, good electrical insulation properties, arc resistance and other characteristics. It also has good processing performance, suitable for secondary processing, applicable for high rigidity and high toughness requirements for production parts.


Product applications

Because of its outstanding characteristics, it is widely used in aerospace, electronic appliances, machinery, auto railway and other industries. It is used in the production of high performance requirements devices with high rigidity, high toughness, high temperature resistance and insulation. And it can also be applied in making high - strength shell, high - temperature resistance contactor, etc.
