PPS-S40GA
Polyphenylene Sulfide (PPS) is a novel high-performance engineering plastic—a polymer whose main chain contains phenylthio groups. Due to its structure, in which benzene rings and sulfur atoms are alternately linked, the molecular chains exhibit significant rigidity and regularity, making PPS a crystalline polymer. It is renowned for its outstanding heat resistance, dimensional stability, mechanical strength, and excellent chemical corrosion resistance.

Polyphenylene Sulfide (PPS) is a novel high-performance engineering plastic—a polymer whose main chain contains phenylthio groups. Due to its alternating structure of benzene rings and sulfur atoms, the molecular chains exhibit exceptional rigidity and regularity, making PPS a crystalline polymer. It is renowned for its outstanding heat resistance, dimensional stability, mechanical strength, and excellent chemical corrosion resistance. Compared with metals or ceramics, PPS-based composite materials can achieve weight reductions of up to 60% while offering lower overall costs, making them suitable for applications such as connectors, protective panels, and power‑unit housings in exoskeletons, as well as gears and bearing components in robotics.
