FFKM Cord Material Description

FFKM Cord

Perfluoroelastomer (FFKM) cord, and FFKM material in general, lasts longer than other standard compounds. FFKM is best used in demanding processing environments such as chemical processing, oil and gas recovery, semiconductor wafer fabrication, pharmaceuticals, and aerospace industries.

The performance longevity of FFKM products can mean infrequent seal changes, repairs, and inspections, thus, increasing process efficiency and productivity with greater equipment run time. FFKM cord resists over 1,800 different chemicals, while offering the high temperature stability of PTFE (327°C).

FFKM is preferred in harsh media, such as:

  • Gasoline
  • Oils
  • Fuel additives
  • Alcohol
  • Acid
  • Hydrocarbons
  • And much more
FFKM parts and seals also help prevent semiconductor process contamination by reducing particulates, lowering extractables, and resisting degradation in harsh plasma. FFKM also provides low outgassing in vacuum-sealing applications.

Our FFKM cord can be vulcanized to your specifications. Global O-Ring and Seal’s FFKM cord maintains FDA compliance and is made here in the United States.
