Oil-Resistant Fluororubber Sheet: Properties and Applications Fluororubber, also known as FKM (fluoroelastomer), is a high-performance synthetic rubber renowned for its exceptional resistance to oils, fuels, chemicals, and extreme temperatures. Oil-resistant fluororubber sheets are widely used in industries where durability and reliability under harsh conditions are critical. These sheets exhibit outstanding mechanical properties, chemical stability, and thermal resistance, making them ideal for sealing, gasketing, and insulation applications. Key Properties 1. Oil and Fuel Resistance Fluororubber sheets demonstrate excellent resistance to a wide range of oils, including petroleum-based lubricants, hydraulic fluids, and automotive fuels. This property ensures long-term performance in environments exposed to hydrocarbon-based substances. 2. Chemical Resistance FKM sheets resist degradation from acids, alkalis, and aggressive solvents, making them suitable for chemical processing, oil refining, and pharmaceutical industries. 3. High-Temperature Stability These sheets can withstand continuous exposure to temperatures ranging from -20°C to +200°C (-4°F to +392°F), with some specialized grades enduring even higher temperatures. This makes them ideal for automotive, aerospace, and industrial applications. 4. Low Compression Set Fluororubber maintains its elasticity and sealing ability even after prolonged compression, ensuring reliable performance in gaskets and seals. 5. Weather and Ozone Resistance Unlike many elastomers, fluororubber resists degradation from UV radiation, ozone, and weathering, making it suitable for outdoor applications. Applications 1. Automotive Industry Used in fuel system seals, O-rings, valve stem seals, and gaskets due to their resistance to gasoline, diesel, and synthetic lubricants. 2. Aerospace and Aviation Employed in fuel hoses, hydraulic seals, and engine gaskets where high-temperature and chemical resistance are essential. 3. Oil & Gas Industry Ideal for sealing applications in pipelines, drilling equipment, and refineries where exposure to hydrocarbons and harsh chemicals is common. 4. Industrial Machinery Used in pumps, compressors, and hydraulic systems to prevent leaks and ensure long-lasting performance. 5. Chemical Processing Suitable for gaskets and linings in reactors, tanks, and piping systems handling corrosive substances. Conclusion Oil-resistant fluororubber sheets are a vital material in demanding environments where resistance to oils, chemicals, and extreme temperatures is required. Their versatility and durability make them indispensable in automotive, aerospace, industrial, and chemical applications. By selecting the appropriate grade and thickness, engineers and manufacturers can ensure optimal performance and longevity in their sealing and gasketing solutions.
