PPS is a plastic material that is often used in applications involving exposure to corrosive chemicals at elevated temperatures. PPS has outstanding mechanical properties and it is resistant to hot water and steam. It exhibits good dimensional stability and high dialectic strength. PPS is widely used for semiconductor machinery components, scientific instrumentation parts, seals, pump, valve, and electrical components.
