Committed to the original development and import substitution of PPS polyphenylene sulfide
Ultra High Wear Resistant Polyphenylene Sulfide
PPS-PAC25 is a 25% carbon fiber reinforced polyphenylene sulfide material with good wear resistance, excellent chemical resistance and heat resistance.
This product is mainly used to make gear, high temperature sleeve, sliding bearing and other products with lower friction coefficient and lower friction consumption requirements.
