PPS Celanese 6165A6

PPS Celanese 6165A6 is a high‑performance polyphenylene sulfide plastic. Its core advantages include high strength, high rigidity, outstanding heat resistance and dimensional stability, together with inherent UL94 V‑0 flame retardancy. It is especially suitable for high‑temperature, high‑load and precision‑dimension applications as a metal‑replacement material.

Main Applications

Automotive Industry: engine‑peripheral components, exhaust‑system parts.

Electrical‑Electronic Industry: electronic connectors, switches, sockets, coil bobbins and other components.

Mechanical & Industrial Components: pump housings, pistons, impellers, valves.
