Description

technical field [0001] The invention relates to a high temperature resistant flame retardant insulating material, in particular to a high temperature resistant flame retardant insulating material for automobile wires. Background technique [0002] According to the requirements of the application environment, automotive wires need to have properties such as heat resistance, flame retardancy, abrasion resistance, oil resistance, and mold resistance. Depending on the environment and location, automotive cables are classified into various temperature classes. At this stage, according to the development trend of the market and the needs of customers, PVC is generally used for insulation of wire products with a grade of 105°C and below, and radiation cross-linked polyolefin materials are used for insulation of automobile wires with a grade of above 105°C. Compared with PVC, the insulating properties, chemical properties, and heat resistance properties of polyolefin materials have...
