ZH-70 70℃ PVC Flame Retardant Soft Sheath Plastic

ZH-70 70℃ PVC Flame Retardant Soft Sheath Plastic has flame retardant properties and softness. It uses PVC (polyvinyl chloride) as the basic material and is processed by a special process. It can work stably at a temperature of 70°C and is wear-resistant and corrosion-resistant. Widely used in wires and cables, automotive interiors, construction pipelines and other fields.

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