PPS (Polyphenylene Sulfide)

PPS (polyphenylene sulfide) is a semi-crystalline high-performance engineering plastic with a continuous use temperature of 200-240°C, maintaining good mechanical strength and rigidity at elevated temperatures.

PPS chemical resistance ranks second only to PTFE; it is almost insoluble in any organic solvent below 200°C. It is naturally flame retardant (UL94 V-0) with extremely low water absorption (under 0.05%), delivering outstanding dimensional stability.

PPS is relatively brittle with edge chipping concerns during machining. We optimize tool geometry and cutting parameters to ensure edge quality, maintaining batch dimensional consistency within ±0.01mm. We specialize in batch production, 100 pcs MOQ, lead time 15-25 days.
