For those seeking a combination of characteristics that include high-temperature resistance and chemical resistance, FKM Rubber – Fluorocarbon is often considered a universal elastomer for its ability to perform in many applications requiring both. Fluorocarbons also display high resistance to swelling when exposed to gasoline and other petroleum products and have a slow degradation rate when used in applications with UV exposure and ozone.
Fluorocarbons are used in many applications that require high-temperature resistance and exposure to corrosive materials such as gas, fuel, and oil where resistance to swell and low compression set are required. These include fuel system seals and hoses, expansion joints, gaskets and shaft seals. They are also used in parts requiring a hard-vacuum set and can meet FDA requirements for pharmaceutical and food applications. Contact us to see if FKM rubber is right for your project.
