PPSU (polyphenylenesulfone)

PPSU is an amorphous plastic. The material combines a high melting temperature with low water absorption.

It also exhibits better impact strength and chemical resistance than PSU. In addition to these properties, PPSU exhibits significantly better hot steam sterilizability and resistance to cleaning agents and disinfectants compared to other representatives of this class of plastics.

Properties

The properties of PPSU are:
  • high service temperature (180°C)
  • good chemical resistance
  • excellent hydrolysis resistance (suitable for repeated steam sterilization)
  • high rigidity over a wide temperature range
  • very high impact resistance
  • high dimensional stability
  • very good resistance to high-energy radiation (Gamma and X-rays)
  • good electrical insulation properties
  • favourable dielectric properties

Applications

The applications of PPSU are:
  • Positioning sleeves for endoscope probes
  • Medical bars
  • Precision components in electrical engineering
