FFKM

FFKM (Perfluoroelastomer)

Ultra-high-performance elastomer for semiconductor process equipment and aggressive chemical sealing.

Answer-First Summary

  • Temperature Range: Up to +320 C, compound-dependent
  • Media Profile: Aggressive process chemicals, plasma-adjacent exposure, and vacuum service
  • Engineering Role: Premium sealing material for low-outgassing, low-contamination process windows

Good Fit

Best fit when downtime, contamination risk, or chemical attack makes standard FKM insufficient.

Typical Application Windows

Semiconductor chamber seals

Chemical process O-rings

Vacuum transfer interface seals
