    Physical Properties

    FFKM is a perfluoroelastomer that contains more fluorine than general fluoroelastomer.
    FFKM is resistant to higher temperatures and various chemicals and can withstand long periods of time even in the presence of plasma. In particular, perfluoroelastomers of a specific grade can be used continuously at up to 327℃, and based on these characteristics, they are used in various industries that require sealing, such as semiconductors and petrochemicals.
