FKM

FKM (Fluoroelastomer)

High-temperature and chemical-resistant elastomer for demanding industrial, automotive Tier 2, and energy-system sealing.

Answer-First Summary

  • Temperature Range: -25 C to +250 C, compound-dependent
  • Media Profile: Fuel, oil, selected chemicals, and high-temperature service conditions
  • Engineering Role: The default severe-duty material before moving into FFKM-level chemistry

Good Fit

Best fit for heat, oils, fuels, coolants, and chemical exposure where general elastomers lose sealing stability.

Typical Application Windows

Thermal-management connector seals

Chemical-contact O-rings

High-temperature molded components
