Fluorocarbon (FPM, FKM, VITON™):

Fluorocarbon is a well- known high performance rubber, and especially it has excellent resistance to high temperature, ozone, weather, oxygen, mineral oil, fuels, hydraulic fluids, aromatics and many organic solvents and chemicals.

Fluorine Content:

Viton™ system gum like general type (A-TYPE, 66% fluorine), middle fluorine content type (B-, GBL-TYPE, 67~68.5% fluorine), high fluorine content type (F-, GF-TYPE,70% fluorine ), improving low temperature flexibility type (GLT-, GFLT) and excellent resistance to more chemicals and solvents– Viton™ ETP Extreme.
We also can supply excellent acid and alkali resistance parts made by AFLAS®.

Cure system–Bisphenol cured vs. Peroxide-Cured:

Standard FKM compounds are Bisphenol cured. FKM compounds with peroxide-cured possess better acid solution resistance than the bisphenol cured, and can replace litharge-cured applied in acid solution. In Some lubricants adding a few organic amide or amine, choosing peroxide curing system Viton™ will be better than bisphenol curing system.

Other Common Variations:

  • FKM can also be submitted for approval to Underwriters Laboratories (UL) for use in applications as prescribed in UL157.
  • FKM has excellent resistance to high temperature, oil, solvent, flame, chemical and weather, and it is usually applied in automotive, chemical processing, aerospace and many industrials.
  • Viton™ GLT is broadly used in thermal range of -40℃to +250℃and it has outstanding resistance to aggressive HTS-type oils which are commonly used in aerospace industry.
  • Viton™ ETP is usually applied in chemical industrial.
  • In some fuels adding several methanol, Viton™ F and B-type are more usable than A-type especially F-type. If it requires lower temperature, GFLT and GBLT will be available.
  • AFLAS® (TFE/propylene polymer) is better base and steam resistant than other general Vitons. It can be use in amine, amide and some bases.
