POLYSULFONE

Made from UDEL^® polysulfone resin, these stock shapes remain stable, resisting creep and deformation under continuous load and elevated temperatures. They have high tensile strength and, as temperatures increase, flexural modulus remains high. Polysulfone products will withstand exposure to soap, detergent solutions and some hydrocarbon oils, even at elevated temperatures under moderate stress levels.

The following physical property information is based on typical values of the base polysulfone resin (PSU).

Advantages of Polysulfone

Hot water & steam performance to 300°F (150°C)
Dimensionally stable
Easily machined
FDA compliant
Transparent grades available
Excellent mechanical and electrical properties
Steam resistant
