PVC (polyvinyl chloride polymer = PVC molecular structure) is a thermoplastic resin polymerized by vinyl chloride under the action of initiator. It is a homopolymer of vinyl chloride. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin. PVC is white powder with amorphous structure, and its branching degree is small. The natural color is yellowish translucent and glossy. The transparency is better than that of polyethylene and polypropylene, and worse than that of polystyrene. Depending on the amount of additives, it can be divided into soft and hard PVC. The soft products are soft and tough, and feel sticky. The hardness of hard products is higher than that of low-density polyethylene, but lower than that of polypropylene. There will be whitening at the inflection point. Common products: plates, pipes, soles, toys, doors and windows, wire skins, stationery, packaging boxes, etc.
