Fluorine rubber is an elastic polymer with fluorine atoms attached to carbon atoms in the main chain or side chain, which is obtained by polymerization or condensation of fluorine monomer. Because of the different fluorinated monomers used in manufacturing, fluorinated rubber has many varieties, which can be divided into fluorinated olefin copolymers and nitroso copolymers. Specifically, according to the chemical composition can be divided into fluorene by fluorine rubber, fluorine silicone rubber, nitroso fluorine rubber, fluorinated acrylic rubber, phosphonitrile fluoride rubber, fluorine ether rubber and so on. Fluorine rubber has the characteristics of high temperature resistance, oil resistance and corrosion resistance of a variety of chemicals. It is an indispensable material for modern aviation, missiles, rockets, space navigation and other cutting-edge science and technology. In recent years, with the continuous improvement of reliability, safety and other requirements of the automobile industry, the use of fluorine rubber in the automobile has also increased rapidly.
