Problems solved by technology
[0002] At present, in the production process of wires and cables, there are strict requirements on the electrical properties of insulating materials. The rubber cables in the background technology generally use ordinary ethylene-propylene rubber as insulating materials. However, some special cables require the adhesion between metal conductors and insulating materials. , Ordinary ethylene propylene rubber has poor self-adhesiveness and mutual adhesion, which cannot meet the process requirements and affect product quality
