VITON fluorine rubber, rubber containing fluorine in the molecule, depending on the fluorine content, that is, the structure of the monomer, there are various types; high temperature resistance is better than silicone rubber. Chemical resistance, resistance to most oils and solvents (except ketones and esters), weather resistance, ozone resistance are good, but cold resistance is poor; generally used in automobiles, motorcycles, etc. The operating temperature range is -20 ℃ ～ 260 ℃. When low temperature is required, a low temperature resistant type can be used. It can be applied to -40 ℃ and the price is higher.
