Greene Tweed CHEMRAZ® 592 Perfluoroelastomer
Categories: Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)

Material Notes: Chemraz® 592, a versatile perfluoroelastomer developed with a proprietary filler system, is very resistant to plasma attack. This compound’s durometer allows for some hardware finish inconsistency and higher sealing loads. It’s well suited for critical seals in static and dynamic dry applications where reliability and purity are equally essential. Chemraz 592 is recommended for applications with service temperatures up to 240°C (464°F).

Applications:

  • Slit valves
  • Lid seals
  • Endpoint windows
  • Valve seals
  • Window seals
  • Isolator valve seals
  • Gas inlet seals
  • Bell jar seals
  • KF fitting seals
