my country’s polyvinyl chloride (PVC) production capacity maintains steady growth and is widely used in

Polyvinyl chloride (PVC) refers to the vinyl chloride homopolymer produced by the polymerization reaction of vinyl chloride monomer under the action of initiator or light or heat. Polyvinyl chloride is synthesized with ABS, polypropylene (PP), polyethylene (PE), and polystyrene (PS) into five general-purpose resins. PVC has the advantages of corrosion resistance, high temperature resistance, flame retardancy, and wear resistance, and is widely used in many fields.

The production methods of polyvinyl chloride mainly include the ethylene method and the calcium carbide method. The ethylene method uses ethylene and chlorine as raw materials, and finally makes polyvinyl chloride through distillation, extraction, absorption, synthesis and other links. The products produced by the ethylene method have higher purity and are the polyvinyl chloride production method most used by overseas companies. Chinese enterprises mostly use the calcium carbide method to produce polyvinyl chloride, with calcium carbide and hydrogen chloride as the main raw materials. This method consumes high energy and can easily cause environmental pollution.

According to the “2022-2027 China PVC Project Investment Feasibility Research Report released by the Industrial Research Center, PVC It has a wide range of applications, including cable materials, building materials, profile doors and windows, shoe materials, pipes and fittings, etc. The demand for pipes and fittings accounts for a relatively high proportion and is the main application field of polyvinyl chloride. Polyvinyl chloride is mainly used to produce plastic products. In recent years, the output of plastic products in our country has continued to grow. According to data from the National Bureau of Statistics, my country’s plastic product output reached 80.040 million tons in 2021, a year-on-year increase of 5.3%. The rapid development of downstream industries has driven the continued growth of my country’s demand for polyvinyl chloride, which has exceeded 21 million tons in 2021.

my country’s polyvinyl chloride production capacity is mainly concentrated in the northwest region. In recent years, benefiting from the continuous optimization of the industrial structure, my country’s polyvinyl chloride production capacity has shown a net growth trend. According to statistics from the China Chlor-Alkali Industry Association, my country’s polyvinyl chloride production capacity will reach 27.13 million tons in 2021, a year-on-year increase of 3.0%. In terms of import and export, my country is a major exporter of polyvinyl chloride, with a large industry trade surplus. According to statistics from the General Administration of Customs of China, my country’s polyvinyl chloride export volume reached 2.094 million tons in 2021, and its import volume reached 561,000 tons.

In terms of market competition, there are many polyvinyl chloride manufacturers in my country and the industry concentration is low. Xinjiang Tianye, Sanyou Group, Chlor-Alkali Chemical, Zhongtai Chemical, etc. are the enterprises with relatively high PVC output in my country. According to the financial report of Zhongtai Chemical Company, the company’s polyvinyl chloride output reached 1.936 million tons in 2021, accounting for 8.4% of the country’s total output, ranking first in the industry.

Industry analysts said that polyvinyl chloride has excellent performance and a wide range of applications. Driven by market demand, my country’s polyvinyl chloride continues to Expansion, production continues to grow. At present, ethylene method and calcium carbide method are the main production methods of polyvinyl chloride. Driven by technological progress and environmental protection policies, the application proportion of ethylene method is expected to further expand. my country’s polyvinyl chloride industry has entered a mature development stage, and driven by leading companies, market concentration will continue to increase.
