Problems solved by technology

[0002] The automobile wiring harness is the main body of the automobile circuit network. It connects the electronic components of various parts of the automobile. The quality of the wiring harness. The automotive wiring harness materials mainly include wires, terminals, sheaths, tapes, etc. In practical applications, the wiring harness materials of suitable materials should be selected according to the working environment and performance requirements of the wiring harnesses of different parts of the car. Traditional wiring harnesses use insulating materials. There are many problems such as poor flame retardancy, easy deformation at high temperature, and short service life, which bring a lot of inconvenience to actual use and even threaten people's life and property safety. Therefore, it is urgent to change the original formula and improve material properties to adapt to automotive electronic devices. Diverse needs of the market
