Fluorine rubber is an elastic polymer with fluorine atoms on the carbon atoms of the main chain or side chain of the molecule obtained by polymerization or condensation of fluorine monomer. It has high temperature resistance, oil resistance, high vacuum resistance, resistance to a variety of chemicals, corrosion resistance, atmospheric aging resistance, good physical and mechanical properties, can maintain good performance at high temperature, and can work for a long time at 200 °C ~ 250 °C. Fluorine rubber is widely used in modern aviation, automobile, shipbuilding, chemistry, petroleum, telecommunications, instruments, machinery and other fields.
