Polysulfone (PSU)

Polysulfone (PSU) is an amorphous, aromatic high temperature plastic. Like PEI, PES and PSU it’s characterized as a cross-resistant, chemcial resistant to most chemicals and flame retardant. PSU has a lower price than PEI and PES, generally slightly inferior properties.

PSU Properties

  • Amorphous structure with a Tg of 190 C
  • Excellent hydrolysis resistance
  • Good chemical resistance
  • Protected from flames
  • High heat resistance
  • Good for microwaves
