In advanced sectors such as aerospace, automotive fuel systems, and chemical fluid transport, sealing materials must endure extreme temperatures, long-term fuel exposure, and complex mechanical stress. Traditional rubbers like NBR or CR often suffer swelling, hardening, and degradation in such harsh environments. Fluorosilicone rubber compound has emerged as a premium elastomer, offering outstanding resistance to fuels, solvents, and temperature extremes.

This material is based on trifluoropropyl methyl siloxane polymers, incorporating fluorocarbon side groups that significantly enhance its chemical resistance. It remains flexible at -60°C and thermally stable up to 200°C, maintaining elasticity across a broad temperature range. Its low compression set makes it ideal for long-term sealing, effectively preventing leakage and media permeation.

Fluorosilicone rubber compounds are widely used in aerospace fuel seals, gasoline pump diaphragms, jet engine gaskets, and chemical transfer hose linings. Particularly in aggressive fuels like aromatic blends, ethanol gasoline, or aviation kerosene, it demonstrates minimal swelling and high mechanical retention, ensuring system durability and reliability.

As industries like new energy vehicles, hydrogen propulsion, military systems, and gas turbines evolve, fluorosilicone rubber is being further enhanced for higher strength, lower volatility, and improved compression recovery. Customized formulations can now be tailored for specific environments, making this material a vital contributor to the safety and performance of next-generation sealing applications.
