Based on pvc resin,Environmental Friendly pvc plastic is a granular material made by mixing, plasticizing, and granulating with plasticizers, flame retardants, stabilizers, and cold resistant additives. PVC plastic has good dielectric properties and is widely used in the insulation layer of wires and cables, as well as in the manufacture of electrical equipment.
This product has good physical and mechanical properties, low-temperature performance, and extrusion processing performance, and is suitable for wire and cable sheath materials with heat resistance temperature of 90 ºC and requirements for cold resistance and flame retardancy.
1. Environmental friendly polyvinyl chloride has good insulation;
2. PVC plastic has weather resistance;
3. Chemical corrosion resistance;
4. Plasticity and flexibility;
1.Insulation and jacketing materials for fiber optic cables;
2. Widely used in pvc pipes, window profiles, films, sheets, tubes, shoes, fittings;
