Product Brochure (40kb - pdf)
|
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). |
