PVC is actually a kind of vinyl polymer, and its material is an amorphous material. In actual use, PVC materials often add stabilizers, lubricants, auxiliary processing agents, pigments, impact resistance agents and other additives. It has non-flammability, high strength, weather resistance and excellent geometric stability. PVC has strong resistance to oxidants, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid and concentrated nitric acid, and it is also not suitable for situations where aromatic hydrocarbons and chlorinated hydrocarbons are in contact. In addition, the term person vs computer in the game is abbreviated as PVC, and PVC human figures are often abbreviated as PVC.

Polyvinylchloride, whose main component is polyvinyl chloride, has bright color, corrosion resistance, and durability. Due to the addition of some toxic auxiliary materials such as plasticizers and anti-aging agents in the manufacturing process to enhance its heat resistance, toughness, ductility, etc., Therefore, its products generally do not store food and medicines. It is a kind of synthetic material that is well-loved, popular and widely used in the world today. Its global usage ranks second among various synthetic materials.

According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, the production and consumption of PVC is an average of 1.4 million tons. PVC is being produced and applied worldwide at a growth rate of 4%. In recent years, the growth rate of PVC in Southeast Asia has been particularly remarkable, thanks to the urgent need for infrastructure construction in Southeast Asian countries. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material. PVC (polyvinyl chloride), its monomer structure is CH2=CHCl.

PVC material has a wide range of uses, with good processing performance, low manufacturing cost, corrosion resistance, insulation and other good characteristics. It is mainly used to produce: Pravin pvc cards; pvc OEM; pvc iron wire; pvc curtains; pvc coated welded wire mesh; pvc foam board, pvc ceiling, pvc water pipe, pvc skirting line, etc., as well as threading pipe, cable insulation, plastic doors and windows, plastic bags, etc. PVC products can be seen everywhere in our daily lives. PVC is used to make all kinds of imitation leather, used in luggage, sports products, such as basketball, football and rugby. It can also be used to make belts for uniforms and special protective equipment.
