What is PVC material?

PVC material is polyvinyl chloride, the price of polyvinyl chloride is relatively cheap, and it is widely used. It is the raw material of plastics. Adding an appropriate amount of plasticizer to polyvinyl chloride resin can make a variety of hard , soft and transparent products. The following editor will give you a detailed introduction to PVC materials.

PVC is actually a vinyl polymer substance, and its material is a non-crystalline material. PVC materials are often added with stabilizers, lubricants, auxiliary processing agents, colorants, impact agents and other additives in actual use. It has non-flammability, high strength, resistance to climate change and excellent geometric stability. PVC has strong resistance to oxidizing agents, 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 not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons. In addition, the term person vs computer in the game is abbreviated as PVC, and PVC figures are often referred to as PVC for short.

PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounts for about 2/3 of the market, and soft PVC accounts for 1/3.
Soft PVC is generally used for floors, ceilings and leather surfaces, but because soft PVC contains a softener (this is also the difference between soft PVC and hard PVC), it is easy to become brittle and difficult to preserve, so its scope of use is limited.

Rigid PVC does not contain softeners, so it has good flexibility, easy to shape, not brittle, non-toxic and pollution-free, and has a long storage time, so it has great development and application value. The essence of PVC is a vacuum blister film, which is used for the surface packaging of various panels, so it is also called decorative film and adhesive film, and is used in many industries such as building materials, packaging, and medicine. Among them, the building materials industry accounts for the largest proportion, 60%, followed by the packaging industry, and several other industries with small-scale applications.
