Typical Properties
PPS is a chemical and corrosion resistant thermoplastic 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. Bearing-grade PPS has excellent wear resistance.

PPS is often used as a lower cost alternative to replace PEEK at low to moderate temperatures.
