PSU (PolySulfone)

PSU is a thermoplastic material with a high mechanical strength and rigidity.

In addition to the high continuous service temperature, the salient features include a remarkably high creep resistance over a wide temperature range.

Due to its amorphous molecular structure PSU is translucent and has a slightly yellowish transparency. A high dimensional stability and very good hydrolysis resistance complete the picture.


The properties of PSU are:
  • High continuous service temperature (160 ° C)
  • Very good hydrolysis resistance (suitable for repeated steam sterilization)
  • High toughness even at low temperatures
  • High dimensional stability
  • High mechanical strength
  • High rigidity
  • High creep resistance over a wide temperature range
  • Very good resistance to high-energy radiation (Gamma and x-rays)
  • Good electrical insulating and dielectric properties


The applications of PSU are:
  • Control valves
  • Distributor
  • Inserts for steam cleaning equipment
  • Medical device components
