Ensinger TECASON™ S Polysulfone (PSU)
Categories: Polymer; Thermoplastic; Polysulfone (PSU)

Material Notes: TECASON™ S is a transparent engineering plastic known for its chemical resistance, rigidity, high-temperature performance, and its ability to operate in an autoclave environment. TECASON™ S is FDA and NSF compliant and holds its excellent mechanical properties over a wide range of temperatures.

  • Autoclave resistance (maintains dimensional stability and mechanical performance through repeated autoclaves)
  • Excellent electrical properties
  • Good chemical resistance (performs well in mineral acids, alkali, salt solutions, and hydrocarbons)
  • Superior resistance to creep
  • FDA and NSF compliant
  • High-temperature performance (has a heat deflection temperature of 345°F and a long-term continuous use temperature of 285°F)
  • Excellent hydrolytic stability
  • High strength and rigidity
  • Flame retardant (rated UL94 V-O)

TECASON™ S' unique combination of chemical and hydrolytic resistance, high-temperature performance, good mechanical properties, and agency approvals make it an excellent choice for applications in pharmaceutical, medical, food service equipment, semiconductor processing, and electronic equipment industries.
