PVC resin powder production capacity is steadily increasing, but the growth rate of production capacity will slow down

Polyvinyl chloride resin (PVC) is one of the five major general-purpose plastics. PVC resin powder is an amorphous, polar polymer with a white powder appearance. PVC resin powder is thermoplastic, acid-resistant, insoluble in water, ethanol, and gasoline, and can swell or dissolve in ethers, ketones, chlorinated aliphatic hydrocarbons, and aromatic hydrocarbons. According to different degrees of polymerization, PVC resin powder can be divided into general-purpose PVC resin powder and special PVC resin powder. PVC resin powder is one of the earliest industrialized resin varieties. With its good corrosion resistance, electrical insulation, and flame retardant properties, PVC resin powder is widely used in many fields such as construction, medical care, wires and cables, automobiles, and electrical appliances.

According to the “2021-2025 China PVC Resin Powder Industry Market Monitoring and Future Development Prospects Research Report released by the Industrial Research Center , since 2016, with the growth of my country’s economy, the market demand for PVC resin powder has continued to increase, the industry’s production capacity has steadily increased, and the industry as a whole is in a boom cycle, with an average annual compound growth rate of nearly 4% from 2017 to 2020. In 2021, with the commissioning of new equipment, PVC resin powder production capacity will be further improved. As of October 2021, the new PVC resin powder production capacity will reach 500,000 tons. It is expected that the annual PVC resin powder production capacity in 2021 will reach 26.2 million tons. , production capacity growth will slow down.

The production process of PVC resin powder can be divided into petroleum route (ethylene method) and calcium carbide route (carbide method). The petroleum route uses petroleum and chlorine as raw materials, and the calcium carbide route uses coal and raw salt as raw materials. At present, PVC resin powder production in Europe, the United States, the Middle East and other regions mainly uses the ethylene method, while domestic PVC resin powder production mainly uses the calcium carbide method, accounting for about two-thirds of the production capacity. The calcium carbide method has the advantages of simple production process, low cost, and low production investment. my country’s calcium carbide production technology is relatively mature, and the energy structure is “poor in oil and rich in coal”. Therefore, the development of the calcium carbide method in my country has raw material advantages.

From the production side, there are a large number of PVC resin powder production companies in my country. At this stage, there are about 70 production companies, mainly including Qingdao Haiwan, Dezhou Shihua, Shandong Xinfa, Shaanxi Jintai, Julong Chemical, Huayi Chemical, etc. enterprise. PVC resin powder has a high regional concentration, with production capacity mainly concentrated in the three major regions of northwest, north and east China. The northwest region is the main production area of ​​PVC resin powder. In this region, Xinjiang and Inner Mongolia have higher production capacity of PVC resin powder. The combined production capacity of the two places accounts for more than 33%.

Industry analysts said that PVC resin powder has excellent performance and a wide range of downstream applications, involving automobiles, construction, medical and other fields. In recent years, In recent years, with the release of downstream market demand, my country’s PVC resin powder production capacity has steadily increased, and the industry as a whole is still in a boom cycle. The regional concentration of PVC resin powder is relatively high. As relevant enterprises are under construction and planned projects are put into operation, my country’s PVC resin powder production capacity will be further improved, and the industry will have broad room for development in the future.
