Fluorosilicone rubber, a high-performance elastomer that combines the benefits of both silicone and fluorinated materials, has seen growing adoption in the aerospace industry in recent years. Known for its exceptional resistance to jet fuel, lubricating oils, and extreme temperatures, fluorosilicone rubber is rapidly replacing traditional materials in aircraft engine seals and fuel system components.

Even under extreme conditions—such as alternating low temperatures at -60°C in high-altitude environments and heat exposure up to 200°C near engines—fluorosilicone rubber maintains excellent elasticity and sealing performance. This durability not only extends the lifespan of critical parts but also significantly reduces maintenance frequency and costs.

The material’s outstanding chemical resistance makes it suitable for use with aviation fuel, hydraulic fluids, and synthetic lubricants, enabling stable operation in chemically aggressive conditions. Several domestic and international aerospace component manufacturers are now leveraging fluorosilicone rubber compounds with enhanced uniformity and filler compatibility to develop customized solutions for O-rings, gaskets, oil seals, and tubing.

As synthesis techniques and processing methods for fluorosilicone rubber continue to advance, the material is becoming more efficient to produce and more environmentally friendly. This progress is further accelerating its adoption across aerospace, defense, and automotive sectors.
