Udel® Polysulfone (PSU)

Solvay's Udel® polysulfone, PSU, is one of the highest performing amorphous thermoplastics on the market and is known for exceptional hydrolitic stability and maintaining properties when exposed to hot water and steam. The unique property set of Udel® makes it a common choice for use in application spaces like plumbing components, repeatable autoclavable medical devices and membranes.

Popular features of Udel® PSU are:
  • Excellent level of chemical resistance for an amorphous polymer
  • Transparent base polymer makes it very colorable
  • Excellent all around physical property profile that delivers dimensional stability at elevated temperatures
  • No adverse change in properties due to repeat autoclave sterilization 
  • High heat deflection (HDT) of 345 °F (174 °C)
  • Extensive list of regulatory listings - FDA, EU, UL, ISO 10993, USP Class VI, and NSF

ResMart stocks a wide variety of Udel® grades in transparent natural, black and glass fiber reinforced varieties. We can also help you get a tailor-made PSU product should one of our stock portfolio products not meet your exact needs. Contact us to learn more!
