Udel^® Polysulfone 
More Versatile Transparent Plastic

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.

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.

Key Features HDT of 174°C (345°F) High strength Good practical toughness Excellent hydrolytic stability Transparent Colorable

Typical Applications Faucet components Hot water fittings Plumbing manifolds Medical devices Membranes for Hemodialysis Water treatment Bioprocessing Food and beverage Gas separation
