FKM Rubber Sheet: Properties and Applications Fluorocarbon rubber, commonly known as FKM, is a high-performance elastomer widely used in demanding industrial applications due to its exceptional resistance to heat, chemicals, and oils. FKM rubber sheets are manufactured from this material, offering superior durability and reliability in harsh environments. Key Properties of FKM Rubber Sheets 1. Temperature Resistance – FKM sheets can withstand extreme temperatures, typically ranging from -20°C to +200°C (-4°F to +392°F), with some specialized grades capable of enduring even higher or lower temperatures. This makes them ideal for applications involving heat exposure. 2. Chemical Resistance – FKM exhibits excellent resistance to a wide range of aggressive chemicals, including acids, fuels, oils, and solvents. Unlike many other elastomers, it does not degrade easily when exposed to hydrocarbons or corrosive substances. 3. Oil and Fuel Resistance – Due to its fluorinated structure, FKM rubber sheets are highly resistant to swelling and degradation when in contact with petroleum-based oils, synthetic lubricants, and fuels. 4. Aging and Weather Resistance – FKM maintains its mechanical properties even after prolonged exposure to UV radiation, ozone, and weathering, ensuring long-term performance in outdoor applications. 5. Low Gas Permeability – The dense molecular structure of FKM reduces gas permeation, making it suitable for sealing applications where preventing leaks is critical. Common Applications of FKM Rubber Sheets - Automotive & Aerospace – Used in fuel system seals, O-rings, gaskets, and hoses due to their resistance to fuels and lubricants. - Oil & Gas Industry – Employed in seals and gaskets for pumps, valves, and pipelines exposed to aggressive chemicals and high temperatures. - Chemical Processing – Ideal for lining tanks, gaskets, and expansion joints in environments with corrosive fluids. - Semiconductor Manufacturing – Used in cleanroom applications where chemical resistance and low outgassing are essential. - Food & Pharmaceutical – Certain FDA-compliant FKM grades are used in equipment where resistance to sanitizing agents is required. Conclusion FKM rubber sheets are a premium choice for industries requiring high-performance elastomers that can endure extreme conditions. Their outstanding resistance to heat, chemicals, and oils, combined with excellent mechanical properties, makes them indispensable in critical sealing and protective applications. Whether in automotive, aerospace, or industrial settings, FKM rubber sheets provide reliable performance and extended service life.
