Udel (PSU : Polysulfone)

Udel® polysulfone (PSU) is a rigid, high-strength, semi-tough, transparent plastic that offers higher heat resistance and better hydrolytic stability than polycarbonate (PC). It retains its good mechanical properties when exposed to steam and other sterilization techniques.


Udel® 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.
