Problems solved by technology

[0002] Polyvinyl chloride is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. Polyvinyl chloride has good mechanical properties, high tensile strength, good impact strength, and excellent dielectric properties. In terms of specific applications, According to the main properties of PVC products, it can be divided into rigid polyvinyl chloride and soft polyvinyl chloride. Among them, rigid polyvinyl chloride is mainly used in construction materials such as pipes and profiles, while soft polyvinyl chloride is mainly used in cables. , hoses, electrical appliances, etc. At present, the thermal stability of PVC products for cable sheaths is poor, and the waterproof and aging resistance properties cannot meet the needs, which need to be improved urgently
