Fluorocarbon (FPM, FKM, VITON®*)
Fluorocarbon is a well-known high-performance rubber that has excellent resistance to high temperature, ozone, weather, oxygen, mineral oil, fuels,
hydraulic fluids, aromatics and many organic solvents and chemicals.
Viton® variations include: general type (A: 66% fluorine), middle fluorine content type (B, GBL: 67 to 68.5% fluorine),
high fluorine content type (F, GF: 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 VITON® TBR.
Cure system: Bisphenol-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 solutions. In some lubricants, adding a few organic amide or amine, or choosing peroxide-cured system Viton® will be better than bisphenol curing systems.
Standard Low Temp: -26°C (-15°F)
Standard High Temp: 232°C (450°F)
