PSU 1000


PSU 1000 Polysulphone stock shapes are produced from non-UV-stabilised polysulphone resin. It offers very good radiation stability, low ionic impurity levels and good chemical and hydrolysis resistance. Compared to PEI 1000, it has a lower property profile, often replacing polycarbonate whenever higher temperature resistance and improved chemical resistance are required. PSU 1000 Polysulphone is commonly used in food processing equipment (milk machines, pumps, valves, filtration plates, heat exchangers) and for medical components* subject to repeated cleaning and sterilisation.

*Please note: this material is not allowed, approved or suitable for human implantable applications.

Main properties of our range of PSU 1000 Polysulphone sheet and rod are:

  • High maximum allowable service temperatures in air (150°C continuously)
  • High mechanical strength, stiffness and creep resistance, also at elevated temperature
  • Excellent hydrolysis resistance (suitable for repeated steam sterilisation)
  • High toughness, even at low temperatures
  • Physiologically inert (suitable for food contact)
  • Very good dimensional stability
  • Translucent, non-optical quality
  • Very good resistance against high energy radiation (gamma and X-rays)
  • Good electrical insulating and dielectric properties

PSU 1000 Polysulphone is available in:

  • Sheet
  • Rod
