The application of fluorosilicone in the aviation industry is mainly reflected in the manufacture of various sealing products, which have excellent resistance to fuel oil, lubricating oil, hydraulic oil, solvents, etc. Specifically, fluorosilicone is used to manufacture various dynamic and static working O-rings, fillers, integral tank seals, sealing rings, sensor materials, diaphragms, fluorosilicone gasket wire clamps, etc.

In addition, fluorosilicone rubber is also used for valves, diaphragms, catheters, films, etc. for aviation membrane pressure regulation, such as diaphragms for valves in tank pressure regulating pipelines, diaphragms for tank ventilation valves, etc.

The reason why fluorosilicone rubber can be widely used in the aviation industry is that it has excellent oil and solvent resistance. This is formed by introducing fluorine-containing groups (such as trifluoropropyl) into the carbon chain of silicone rubber. The fluorine atom has a great electron-withdrawing effect, and the short bond length of the C-F bond can form a good shielding effect on the C-C bond, thereby greatly improving the oil and solvent resistance of the rubber.

In general, the application of fluorosilicone in the aviation industry is mainly due to its excellent oil and solvent resistance and its wide application in the manufacture of sealing products.
