JR-70 70℃ PVC Flame Retardant Flexible Insulation Compound

JR-70 70℃ PVC Flame Retardant Flexible Insulation Compound is a high-performance insulation material whose key characteristics are its flame retardancy and softness. Based on PVC resin, it is carefully processed by adding plasticizers, stabilizers, flame retardant additives and other processing aids. It can maintain stable insulation performance at temperatures up to 70°C and has flame retardant properties, effectively preventing fires. Its soft texture makes the material easy to process and use, and it is widely used in the insulation layer of power cables, marine cables and other wires and cables.

1. Flame retardant PVC insulating material for wires and cables

Flame retardant PVC insulating material for wire and cable is a granular material prepared by mixing, plasticizing and granulating with polyvinyl chloride resin as the base material, adding plasticizers, stabilizers, flame retardants and other additives.
