Fluorosilicone rubber is a special elastic material with silicon oxygen bonds as the main chain and fluorine containing groups introduced into the side chains, which combines the advantages of organic silicon materials and organic fluorine materials. Its molecular structure endows it with excellent high and low temperature resistance and environmental aging resistance, while exhibiting outstanding stability to non-polar media such as petroleum based fuels, lubricants, hydraulic oils, etc.

Fluorosilicone rubber can maintain elasticity in the extreme temperature range of -60 ℃ to 200 ℃, making it an indispensable high-performance elastic material in modern industry.

The core performance advantages of fluorosilicone rubber are mainly reflected in its oil resistance and chemical stability. The material has excellent resistance to aliphatic, aromatic, and chlorinated hydrocarbon solvents, and can maintain stable physical properties even under long-term exposure to petroleum based fuel oils, lubricants, or hydraulic oils at high temperatures.

Experimental data shows that after soaking fluorosilicone rubber in diesel, gasoline, and synthetic lubricants for 500 hours, its hardness change rate is less than 10%, the volume expansion rate is controlled within 5%, and the tensile strength retention rate exceeds 85%. This characteristic makes it an ideal material for key components such as engine seals and fuel lines.

In the aviation industry, fluorosilicone rubber is the core sealing material for aircraft fuel systems and hydraulic systems. The O-ring, gasket, and sealing ring made of it can directly contact JP series aviation kerosene and maintain sealing reliability in a wide temperature range of -55 ℃ to 200 ℃.

In the automotive industry, components such as engine crankshaft oil seals and transmission sealing rings are made of fluorosilicone rubber, which can withstand high temperatures above 150 ℃ and long-term erosion from API GL-5 gear oil, with a service life exceeding 100000 kilometers.
