Fluorine is added to thermoset elastomers creating Fluoroelastomers. It?s generally composed of vinylidene fluoride (VF2), hexafluoropropylene (HFP), containing 66% ? 70% fluorine. And other components are added to improve different properties, like tetrafluoroethylene, which offers better chemical resistance and perfluoromethylvinyl ether (PMVE) which improves FKM?s low temperature properties.
Excellent resistance to chemicals, oil, ozone and sunlight. Can be used in petroleum oils and fuel, non flammable hydraulic fuels, acids, aircraft engine applications, synthetic hydraulic fluids, organic solvents, mineral and vegetable oil and grease, aliphatic hydrocarbons (butane, propane, natural gas), hard vacuum applications, silicone oils and greases, solvents and water or steam (up to 400°F).
Cannot be used in amines, glycol based brake fluids, methanol, ammonia gas, amines, alkalis, hydrocarbons, ketones, low molecular weight esters and ethers, fireproof hydraulic fluids, formic and acetic acids.
