SPEC SHEET: Fluorocarbon (FPM, FKM, VITON®) 90 Durometer.pdf

Fluorocarbon (FPM, FKM, VITON^®*)

Material Description

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.

Fluorine Content

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.

Temperature Range:

Standard Low Temp: -26°C (-15°F)

Standard High Temp: 232°C (450°F)
