PPS

HPMs – High-performance materials

PPS

Polyphenylene sulphide is a partially crystalline thermoplastic that is suitable for use at high temperatures. Its chemical structure makes it extremely durable. It retains its great mechanical strength at temperatures above 200 °C. The material is electrically insulating and dimensionally accurate, and it has low water absorption. We deliver PPS as plastic sheets and rods.
