Description

Technical field [0001] The invention relates to the technical field of cable materials, and belongs to an environmentally friendly water-resistant polyvinyl chloride cable insulating material. Background technique [0002] Polyvinyl chloride cable materials are widely used because of their good processing properties, good mechanical properties, and good electrical properties, especially because of their low price and large market supply. General PVC cable materials have been able to meet the conventional needs. Polyvinyl chloride insulated cable and wire products are divided into non-sheathed cables for fixed wiring, sheathed cables for fixed wiring, light non-sheathed flexible cables, general-purpose sheathed flexible cables, installation wires and shielded wires, and special-purpose sheathed flexible cables. Cables, PVC insulated flame-retardant / fire-resistant cables and other products. However, with the expansion of wire and cable applications, the requirements for PVC cable...
