PVC is a vinyl polymer material, a non-crystalline material based on PVC resin; and because PVC is a material composed of compounds with relatively high molecular weight, PVC is a polymer material. In actual use, it is mixed with stabilizers, plasticizers, fillers, colorants and modifiers, and then processed by plasticization and molding.

　　PVC can be divided into hard PVC and soft PVC. The difference between soft PVC and hard PVC is that soft PVC is added with a "softener". Rigid PVC has good tensile, flexural, compressive and impact resistance, and can be used as a structural material alone. The advantages of soft PVC: good flexibility, easy to shape, not easy to be brittle, non-toxic and pollution-free, and long storage time. There are many products made of soft PVC, such as PVC transparent film, PVC blister roll and PVC soft plastic refrigerator magnet, so PVC is sometimes called PVC soft plastic. Products made of hard PVC include PVC transparent matte film, PVC matte white product packaging, PVC color film, PVC decorative board, PVC drum skin, etc.

　　 PVC, or polyvinyl chloride, is a plastic product synthesized from 43% oil and 57% salt. PVC is more effective in applying raw materials and reducing fuel consumption. At the same time, the energy consumption of PVC manufacturing is also very low. And in the later use of PVC products, it can be recycled and converted into other new products or incinerated to obtain energy.
