Fluorosilicone rubber introduces trifluoropropyl groups into its side chains, combining the temperature-resistant elasticity of silicone rubber with the oil resistance of fluororubber. It can withstand erosion from non-polar media such as aviation kerosene and hydraulic fluid over long periods within a range of -60°C to 200°C, with minimal compression set. Thanks to this unique advantage, it is widely used in aviation fuel line seals, automotive turbocharger hoses, and chemical valve gaskets, serving as a core elastomer in fuel system sealing applications.
