FFKM (Perfluoroelastomer) seals are distinguished by their excellent chemical resistance and suitability for extreme temperatures ranging from -25 °C to 325 °C. They offer exceptional resistance to a variety of chemicals, including mineral oils, fuels, amines, and moderate acids. FFKM is ideal for demanding applications in industry where high resistance and durability are required.
