[0002] PVC's main component is polyvinyl chloride, a slightly yellowish, transparent material with a glossy appearance. Its transparency surpasses that of polyethylene and polypropylene. Depending on the amount of additives used, PVC is classified as soft or rigid. Soft PVC products are flexible and tough, with a sticky feel, while rigid PVC products have a harderness than low-density polyethylene but lower than polypropylene, and may exhibit whitening at flexural points. Common products include: sheets, pipes, shoe soles, toys, doors and windows, wire sheathing, and stationery. It is a polymer material where one chlorine atom replaces one hydrogen atom in polyethylene. Due to its high transparency, high temperature resistance, and high tensile strength, PVC is commonly used to make packaging films. These films are used for wrapping to make packaged goods more secure and neat, and are applied in industries such as export trade, papermaking, hardware, plastics and chemicals, building materials, food, and pharmaceuticals.
