Polysulfone (PSU) is a rigid, high-strength tough transparent thermoplastic that offers good heat resistance for continuous use up to 300°F (149°C). It is resistant to oxidation and hydrolysis and withstands prolonged exposure to high temperatures and repeated sterilization. Polysulfone is also highly resistant to degradation by gamma or electron beam radiation. Electrical properties are stable over a wide temperature range and after immersion in water or exposure to high humidity.
Polysulfone excels in many fluid-handling applications and has successfully replaced brass in pressurized hot water applications for over 20 years. It exhibits low creep under a sustained load at elevated temperatures and can withstand continuous exposure to hot chlorinated water.
Our extruded stock shapes of the following grades provide a wide range of performance options for demanding applications:
