PVC is polyvinyl chloride plastic, bright color, corrosion resistance, firm and durable. Due to the addition of plasticizer, anti-aging agent and other toxic auxiliary materials in the manufacturing process, its products generally do not store food and drugs.

PVC cable material is PVC based resin, adding stabilizer, dioctyl phthalate, diisodecyl phthalate, dioctyl terephthalate, trioctyl metaphenolate and other plasticizers, calcium carbonate and other inorganic fillers, additives and lubricants and other additives, after mixing kneading and extrusion prepared particles.

PVC cable material has low price and good performance. It plays an important role in wire and cable insulation protection material for a long time. However, this material contains harmful substances to the environment and human body, and there are many problems when it is applied in special environment.

At present, plastic accounts for 91 percent of the cladding materials, and polyvinyl chloride accounts for 80 percent of the plastic. Polyvinyl chloride (PVC) is a chlorine-containing polymer. It has good flame retardant performance and various properties required by cable production and use. It is one of the most widely used plastics in the world.
