polysulfone

Download Datasheet (pdf 40kb)

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. Thermalux® 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).

Thermalux®

Applications Include:
Float switches
Membrane cartridge filter system
Solenoid valve body
Dairy connectors

Advantages of Thermalux®
Dimensionally stable
Easily machined
FDA compliant
Transparent grades available
