The natural color of polyvinyl chloride (PVC) is yellowish translucent and shiny. The transparency is better than polyethylene and polypropylene, but worse than polystyrene. It can be divided into soft and hard polyvinyl chloride according to the amount of additives. 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. Whitening will occur at the bend.

Common PVC products: plates, pipes, soles, toys, doors and windows, wire skins, stationery, etc. It is a polymer material that uses a chlorine atom to replace a hydrogen atom in polyethylene.
