PPS

PPS is an oxidation- and hydrolysis resistant plastic, which can be used for applications with a service temperature of up to 260°C. PPS has a low sliding friction coefficient and a high abrasion resistance. No water absorption, excellent dimensional stability as well as oil and fuel resistance are further properties. Because of the high hardness tight tolerances are possible.

  • Hydrolysis resistance (no water absorption)
  • Excellent dimensional stability
  • Oil and fuel resistance
  • Application areas:
  • Connectors
  • Sensor casings
  • Parts for electric furnaces

PPSU

PPSU belongs to the group of the amorphous high performance thermoplastics with very good mechanical, electrical and thermal properties for applications with higher service temperatures combined with mechanical stress.

  • Most important properties:
  • Temperature resistance (up to 210°C)
  • High impact resistance
  • High chemical resistance
  • Excellent hydrolysis resistance
  • Better impact resistance than PEI and PSU
  • Application areas:
  • Medical equipment manufacture
  • Pharmaceutical equipment manufacture

PSU

Similar to PPSU and PEI, PSU belongs to the group of the amorphous high performance thermoplastics with very good mechanical, electrical and thermal properties for applications with higher service temperatures combined with mechanical stress.

  • Most important properties:
