Problems solved by technology

[0002] With the gradual development of the cable industry, cables are used in all aspects of people's lives. For cables used in high-temperature environments, higher requirements are placed on the high-temperature resistance, heat insulation and mechanical properties of cable materials. Existing The high temperature resistance and mechanical properties of cable materials can no longer meet the requirements of high temperature environments, so it is necessary to propose a new tear-resistant and heat-insulating rubber cable material
