Problems solved by technology

[0002] With the development of the economy, the demand market for cables is broad, which promotes the progress of the production technology of cable materials. Cable materials are not only widely used, but also have special requirements for their performance indicators, such as insulation, tensile strength, service temperature, and flame retardancy. There are strict requirements on performance and other indicators. Continuously improving the performance of cable materials is an urgent need for economic and social development. Traditional cable materials often have poor flame retardancy, high temperature deformation, poor mechanical properties, poor waterproof performance, and long service life. Short and other problems bring a lot of inconvenience to actual use, and even threaten the safety of people's lives and property. Therefore, it is urgent to change the original cable material formula and improve material performance to meet the diverse needs of the cable market.
