Sustason PSU 1000 Polysulphone



Sustason PSU 1000 Product Description


Sustason PSU 1000 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 Susta PEI 1000, Sustason PSU 1000 has a lower property profile and often replaces polycarbonate when higher temperature resistance, improved chemical resistance or autoclavability are required.


Plastics Applications:

  • Electrical industries
  • Coil bobbins, insulating bushings, housings...
  • Process equipment
  • Milking machines, pumps, valves, filtration plates, heat exchangers...
  • Food processing / Medical industries
  • Physiologically inert
  • Components subjected to repeated cleaning and sterilisation
