Fluorosilicone rubber is a fluorine-containing polysiloxane with Si-O as the main chain structure and -CH2-CH3-CF3 as the side chain. Fluorine is the most electronegative element, the C-F bond is quite stable, and the heat resistance is high.
Therefore, fluoro silicone rubber maintains a series of excellent properties such as high and low-temperature resistance, resilience, compression recovery, weather resistance, electrical properties, and mold release properties of silicone rubber. It also has the solvent resistance and fuel oil resistance of fluororubber.
Compared with fluororubber, the fluorosilicone rubber properties are excellent. The fluorosilicone rubber has a better compression set and cold resistance, and can show superior performance from low temperature to high temperature. Fluorosilicone rubber is one of the synthetic rubbers with the best comprehensive performance in the world.
Fluorosilicone rubber is made by adding incremental fillers, reinforcing fillers, structure control agents, modified additives, vulcanizing agents, operating agents, etc. to the raw fluorosilicone rubber, and then vulcanized. At present, the fluorosilicone rubber that is mass-produced and widely used is mainly poly (3,3,3-trifluoro propyl methyl) silicone rubber.

Fluorosilicone rubber has excellent comprehensive properties and meets the requirements of environmental protection and energy-saving. Its raw rubber has many varieties and various processing methods, so its products have a wide variety of products. Fluorosilicone rubber can be applied in a wide range of fields, of which aerospace and automobile industry are the two most important application fields. The application fields are gradually extended to many other fields, such as precision machinery, electronic communication, oil refining and chemical industry, construction, medical machinery, health, electric power, shipping and other fields.
