Polyvinyl chloride, abbreviated as PVC (Polyvinyl chloride polymer = PVC molecular structure), is a thermoplastic resin that is polymerized by gas ethylene under the action of an initiator. It is a homopolymer of vinyl chloride. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin. PVC is a white powder with an amorphous structure with a small degree of branching. Polyethylene refers to a polymer material, which is used to manufacture tubes, rods, plates, films, hollow products and various industrial and agricultural products and daily necessities. Asia is the region with the highest demand for PVC, accounting for more than 65% of the global demand for PVC. This is mainly due to the fact that China drives most of the demand. Global demand for polyvinyl chloride has shown a rise, with an average annual growth rate of 5% during 2018-2024. In the past 17 years, China's PVC resin production reached 16.296.1 million tons, an increase of 6.5% compared to the same period in 2017. Since 2011, China's PVC resin output has maintained a steady growth overall, with output exceeding 10 million tons. However, the growth rate of PVC resin production fluctuates greatly, alternating every year. In 2014 and 2017, the growth rate rose faster, 14.6% and 16.1% respectively; in 2017, the domestic PVC production capacity was 23.92 million tons /year. In the first half of the year alone, the new production capacity of polychlorinated Zene was 860,000 tons/year, with 350,000 tons/year exited, and a net increase of 510,000 tons/year. All exited production capacity was calcium carbide production equipment. The overall capacity expansion of the industry has slowed down significantly, but the trend of stable and increasing capacity continues. Although the growth rate of PVC resin production declined in 2017, the output was still the highest in recent years, reaching 16.2961 million tons.
According to the "2019-2025 China PVC Market In-depth Investigation Research and Development Prospect Analysis Report" released by China Industry Research Network, in the face of the continuous downturn of the domestic PVC market, opening up the foreign trade market is regarded as opening up the difficulties of the PVC industry. The method of the bureau. With the efforts of the whole industry, my country's PVC foreign trade market performed well in the first half of the year. In terms of imports, due to the reduction in the supply of PVC exports from the United States and the increase in international ethylene prices, the competitiveness of foreign sources has weakened, and my country's imports of pure PVC powder have shrunk significantly. In the second half of the year, the factors affecting my country's PVC foreign trade market are still complex. On the one hand, as the operating rate of PVC plants in the United States continues to increase, external market competition is bound to intensify. Affected by this, my country's imports of PVC may increase. On the other hand, as of 2019, the price of raw material ethylene is temporarily high and there is room for downside, while the domestic PVC market price continues to rise, and the competitive advantage of external source prices is slowly recovering, which will to a certain extent export my country's PVC The market has an impact. Since the outbreak of the international financial crisis, great changes have taken place in the global market and trade environment, trade protectionism in various countries has risen, and trade frictions against Chinese enterprise products have increased significantly. This trend will not change in recent years. On the whole, the domestic PVC foreign trade in the second half of the year showed a recovery growth in imports and a steady shrinking in exports. The domestic PVC industry will face a relatively difficult situation. The development of foreign trade and the full use of international and domestic resources and markets will effectively solve the problem of the way out for my country's PVC. In order to cope with the complex and changeable international situation, domestic PVC enterprises should be both internal and external. Internally, it actively researches and develops new products and advances into refined and high-end markets; externally, it formulates reasonable development plans, vigorously expands the international market, especially emerging markets such as India, and accelerates the internationalization of the product market.
