High Temperature Resistant Fluororubber Sheet: Properties and Applications Fluororubber, also known as FKM (fluoroelastomer), is a synthetic rubber material renowned for its exceptional resistance to high temperatures, chemicals, and oils. High-temperature resistant fluororubber sheets are widely used in demanding industrial applications where durability and performance under extreme conditions are critical. Key Properties 1. High-Temperature Resistance Fluororubber sheets can withstand continuous temperatures ranging from -20°C to +200°C, with some specialized grades enduring short-term exposure up to 300°C. This makes them ideal for applications involving heat, such as gaskets, seals, and insulation in engines, aerospace components, and industrial machinery. 2. Chemical and Oil Resistance FKM exhibits excellent resistance to fuels, oils, acids, and solvents, outperforming many other elastomers. This property ensures long-term reliability in automotive, petrochemical, and chemical processing industries. 3. Mechanical Strength and Flexibility Despite their high-temperature and chemical resistance, fluororubber sheets maintain good elasticity and mechanical strength, allowing them to function effectively as seals and gaskets under dynamic conditions. 4. Low Compression Set Fluororubber retains its shape and sealing properties even after prolonged exposure to high temperatures and pressures, reducing the need for frequent replacements. 5. Weather and UV Resistance FKM sheets resist degradation from sunlight, ozone, and weathering, making them suitable for outdoor applications. Common Applications - Automotive Industry: Used in fuel systems, valve stem seals, O-rings, and turbocharger hoses due to their resistance to heat and hydrocarbons. - Aerospace: Critical for seals in jet engines and hydraulic systems where extreme temperatures and pressures are encountered. - Oil & Gas: Employed in drilling equipment, pipeline seals, and refinery components due to their resistance to aggressive chemicals. - Industrial Machinery: Used in high-temperature gaskets, pump seals, and conveyor belts where durability is essential. - Semiconductor Manufacturing: Fluororubber sheets are used in cleanroom environments due to their low outgassing properties. Conclusion High-temperature resistant fluororubber sheets are indispensable in industries requiring reliable performance under harsh conditions. Their unique combination of heat resistance, chemical stability, and mechanical strength makes them a preferred choice for critical sealing and insulation applications. Whether in automotive, aerospace, or heavy industry, FKM sheets ensure long-lasting performance, reducing downtime and maintenance costs.
