resin family

Polysulfone (PSU)/Polyethersulfone (PES)

All Resin Families

Polysulfone (PSU) and Polyethersulfone (PES) offers excellent heat-resistance and transparency. Its wide spectrum of beneficial properties allows them to be molded into high-quality engineering parts and high-load mass-produced articles. It can be successfully used for applications in which other plastics, e. g. polyamide, polycarbonate, and polyoxymethylene, fail to meet the requirements.

Polymer Characteristics

  • High strength
  • High HDT 325-400°F
  • Long term CUT 320-360°F
  • Low creep
  • Good chemical resistance (especially to acids)
  • Excellent hydrolytic stability
  • Transparent
  • Dimensional stability

The exceptional property spectrum of these materials even allows them to replace thermosets, metals and ceramics.

Grades

  • Glass-filled grades
  • Powder flake grades

Processing Methods

  • Injection Molding
  • Extrusion
  • Film
  • Coating Applications
