PVC itself is a high-purity polymer. Acid and alkali corrosion resistance, can be processed into any shape, good quality, low price, is the second largest amount of synthetic plastics products. The number of products made of PVC is equivalent to all the products of a Wal-Mart. PVC itself cannot be said to be toxic. Only when its components decompose and fission will it release mild substances, and its chemical properties are stable at room temperature.
PVC material is PVC, which is one of the largest plastic products in the world. It is cheap and widely used. PVC resin is white or light yellow powder, which cannot be used alone and must be modified. PVC is a white powder with amorphous structure, with low branching degree and poor stability to light and heat. Different additives can be added according to different uses, and PVC plastics can show different physical and mechanical properties. Adding a proper amount of plasticizer into PVC resin can make various hard, soft and transparent products.
PVC is completely nontoxic and tasteless, and has no irritation to human skin or respiratory system. For people who are allergic to wood and paint, furniture or kitchenware packed with PVC film is very suitable. By using PVC film as decorative film, people can avoid using a large number of medium density fiberboard, particleboard, plywood and fiberboard, reduce the use of wood, and thus reduce the damage to forests and even the environment.
The use of PVC once caused great controversy in western countries, and many people tried to replace PVC with various other materials. But it turns out that the quality of PVC is not worse than other substitutes, and the cost is cheaper than these materials.
