PPS BZ-EGC132

Conductive PPS

Product features

This kind of product is one of the conductive modified polyphenylene sulfide (PPS) compounds manufactured by our company, it is made by mixing glass fiber, conductive materials and related additives on the basis of PPS resins. It has electric conduction property, high temperature resistance,creep resistance, chemical corrosion, flame retardant and other characteristics. In addtion, it has good processing performance and low molding shrinkage.

Product applications

Because of its outstanding characteristics of electric conduction property, it is widely used in the automotive, electronics, electrical appliances and chemical industries for making components for conductive requirements.
