Polyoxymethylene (POM) is mainly concentrated in the low-end field. Domestic high-end products still rely on imports.

Polyoxymethylene (POM), also known as acetal resin and polyoxymethylene, is a linear polymer with high density, high thermoplasticity and high crystallinity. According to different properties, polyoxymethylene can be divided into two categories: homopolymer and copolymer. Polyformaldehyde has the characteristics of high crystallinity, high melting point, good thermal stability, strong bending resistance, and good fatigue resistance. It is widely used in electronic appliances, automobile industry, machinery industry, medical equipment and other fields.

my country’s polyacetal industry started around 1950. At first, due to factors such as low production technology and unstable products, the domestic polyacetal industry developed slowly. In recent years, as domestic companies continue to introduce and break through key technologies, domestic polyformaldehyde production capacity has continued to increase, showing a stable growth trend, and the industry has good development prospects. In June 2022, China’s Xinjiang Xinlianxin Energy and Chemical Co., Ltd. planned to build a polyoxymethylene (POM) project with an annual output of 60,000 tons. In the future, as domestic companies continue to build and expand polyoxymethylene projects, it is expected that the domestic polyoxymethylene production capacity will reach 2023. 650,000 tons.

According to the “2022-2027 China Polyoxymethylene (POM) Industry Market In-depth Research and Development Prospects Forecast Report” released by the Industrial Research Center It shows that the upstream of the polyformaldehyde industry chain is a supplier of raw materials and production equipment, mainly including raw materials such as formaldehyde, parformaldehyde, and catalysts, as well as production equipment such as flash concentration equipment, polymerization reactors, extruders, separators, and granulators. ; The midstream is polyformaldehyde production enterprises, mainly including Longyu Chemical, Yuntianhua, Baotailing, Ningxia Coal, Tangshan Zhonghao, Tianye Chemical, Yankuang Lunan, etc.; the downstream is the application market, mainly including automobiles, electronic appliances, Machinery manufacturing, medical equipment, etc.

At present, copolymer acetal is the mainstream product in my country’s polyacetal market, and its output accounts for nearly 90% of the total domestic output. However, because copolymerized formaldehyde has poorer molecular chain structure symmetry than homopolymerized formaldehyde, and has lower crystallinity, melting point, product reliability and other properties, copolymerized formaldehyde is only suitable for low-end fields. At present, domestic polyformaldehyde products are concentrated in low-end fields. Market penetration in high-end fields such as automobiles and precision electronic products is low, and high-end products still rely on imports. In the future, domestic polyformaldehyde companies will need to continue to increase investment in technology research and development to improve their core competitiveness, thereby accelerating the import substitution process in the domestic high-end polyformaldehyde market. The domestic polyformaldehyde industry has broad development space.

Industrial analysis personnel said that in recent years, with the continuous development of domestic electronic appliances, automobiles and other industries, the domestic market demand for polyformaldehyde has continued to increase. , the industry has broad development prospects. However, at present, domestic polyformaldehyde products are still concentrated in the low-end field, and the high-end market penetration rate is low. In the future, domestic polyformaldehyde companies will need to continue to improve their production technology levels, thereby accelerating the import substitution process in the domestic high-end market. The automobile industry will be the market segment with the most applications and the fastest growth of polyoxymethylene in the future. Driven by the continued growth of market demand in the future, my country’s polyoxymethylene industry still has a lot of room for development, and the industry has huge development potential.
