Kalrez® perfluoroelastomer parts

Kalrez® perfluoroelastomer parts, from DuPont Performance Elastomers, have been field proven in highly aggressive sealing environments for more than 30 years. Our parts can help improve sealing reliability in photovoltaic processes that use plasma, high heat and aggressive chemicals. Kalrez® seals resist over 1,800 chemicals including reactive gases and plasmas, alkalis, acids and solvents. Even in contact with these corrosive chemicals, Kalrez seals retain their elastomeric properties at temperatures as high as 325°C.

Kalrez® parts are proven to provide:

  • Excellent resistance to aggressive chemicals including reactive gases and plasmas, alkalis, acids and solvents
  • Outstanding thermal stability to 325C

In wafer based or thin film processes Kalrez® parts help:

  • Improve uptime
  • Extend mean time between seal replacement
  • Lower cost of ownership
