Description

technical field [0001] The invention relates to the technical field of cable sheaths, in particular to an oil-resistant and corrosion-resistant cable sheath material. Background technique [0002] Chlorosulfonated polyethylene is produced by chlorination and chlorosulfonation of low-density polyethylene or high-density polyethylene. It is a white or yellow elastomer, soluble in aromatic hydrocarbons and chlorinated hydrocarbons, insoluble in fats and alcohols, can only swell but not dissolve in ketones and ethers, has excellent ozone resistance, atmospheric aging resistance, and chemical corrosion resistance etc., good physical and mechanical properties, aging resistance, heat resistance and low temperature resistance, oil resistance, flame resistance, wear resistance and electrical insulation resistance. However, only a few countries in the world, such as the United States, Japan, Russia, and China, have installed devices, and the total global annual production capacity is...
