Problems solved by technology

[0004] With the development of my country's modern industry, cables are used in all aspects of the national economy and people's lives, but cables are often subject to friction and stretching during use, which requires improving the wear resistance, stretch resistance and resistance of cable materials. Tear performance, and the addition of flame retardants will reduce the mechanical properties of the cable material, reducing its toughness and impact resistance, making it easy to tear
