PVC material is polyvinyl chloride. It is one of the largest plastic products in the world. It is cheap and widely used. Polyvinyl chloride resin is white or light yellow powder. It cannot be used alone and must be modified. PVC is a white powder with an amorphous structure, with a small degree of branching, and poor stability to light and heat. Different additives can be added according to different purposes, and PVC plastics can present different physical and mechanical properties. Adding an appropriate amount of plasticizer to the polyvinyl chloride resin can be made into a variety of hard, soft and transparent products.

The density of pure PVC is 1.4g/cm³, and the density of PVC plastic parts added with plasticizers and fillers is generally 1.15-2.00g/cm³. PVC products Rigid polyvinyl chloride has good tensile, bending, compression and impact resistance, and can be used as a structural material alone. The flexibility, elongation at break, and cold resistance of soft PVC will increase, but the brittleness, hardness, and tensile strength will decrease. Polyvinyl chloride has good electrical insulation properties, can be used as low-frequency insulation material, and its chemical stability is also good. Due to the poor thermal stability of polyvinyl chloride, long-term heating will cause decomposition, release HCL gas, and make polyvinyl chloride discolor, so its application range is narrow, and the use temperature is generally between -15 and 55 degrees. PVC is polyvinyl chloride, a plastic product synthesized from 43% oil and 57% salt. Compared with other types of plastic products, PVC uses raw materials more effectively and reduces 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.
