PVC, full name polyvinyl chloride (Polyvinyl chloride), is an important plastic material with many excellent properties, such as corrosion resistance, high temperature resistance, wear resistance, aging resistance, good flexibility and so on. It is widely used in industry, construction, medical, electronics, packaging and other fields, and is widely used in the manufacture of daily necessities, pipelines, building materials, electrical cables, oil pipelines, etc.

PVC is one of the most widely used synthetic plastics in the market, and it is also a thermoplastic. It can be formed by heating and plastic processing, and can be used to meet different application properties and requirements by adding different additives and modifiers. The performance and application scenarios of

PVC products are mainly manifested in:

1. Strong ozone resistance: PVC will be affected by solar ultraviolet rays when used outdoors, and will crack and harden. However, after special formula and modification, PVC will greatly improve ozone resistance, making it can be used outdoors for a long time without quality problems, such as PVC cable sheath.

2. Good chemical resistance: PVC has high chemical resistance, can withstand strong acid and alkali corrosion, good corrosion resistance, and resistance to corrosion and corrosion of various chemicals and oil products, it has good corrosion resistance (such as chemical pipelines and anti-corrosion repair materials used in chemical industry);

3. Good mechanical properties: PVC is a relatively flexible material, and it has strong strength and hardness, and has good extensibility and compressibility, which can achieve good cushioning and shockproof performance, suitable for the manufacture of high-strength, impact-resistant materials (such as car seals, molded artificial leather, etc.);

4, good flame retardancy: PVC is a good flame retardant material, by adding flame retardant, made of flame retardant cables, building materials and other products, and can pass the self-extinguishing test. This plays an important role in construction and electrical products;

5, protect the environment: some PVC plastic products contain halogen, which has a greater impact on the environment. However, the current technology has been able to be processed through the production process to reduce the halogen content of PVC plastics and achieve green production.

PVC is a widely used plastic material, which has important uses in many industrial and consumer fields. Although there are some problems that can not be ignored in the use of PVC products, the market demand and technological progress will inevitably promote the new progress and development of PVC plastic products.
