TECASON S Polysulfone

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
    TECASON™S maintains dimensional stability and mechanical performance through repeated autoclaves.
  • Excellent electrical properties
  • Good chemical resistance
    TECASON™S performs well in mineral acids, alkali, salt solutions, and hydrocarbons.
  • Superior resistance to creep
  • FDA and NSF compliant
  • High-temperature performance
    TECASON™S 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
    TECASON™S is rated UL94 V-O

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