Unsaturated polyester resin has undergone adjustments and has great potential for future industry development

Unsaturated polyester resin is a kind of thermosetting resin. It is generally a linear high-quality linear resin with ester bonds and unsaturated double bonds formed by the condensation polymerization of unsaturated dibasic acid and diol or saturated dibasic acid and unsaturated diol. Molecular compounds. It is a resin solution with a certain viscosity formed by diluting cross-linking monomers or active solvents, referred to as UPR. Unsaturated polyester resin has strong mechanical properties, is resistant to chemical corrosion, can be cured at room temperature and pressure, has excellent electrical properties, and has good process performance. Its products are widely used in petrochemical, machinery, automobile, metallurgy and other industries.

As a major chemical producer in the world, China not only has a relatively complete industrial chain, but also has strong independent capabilities in raw material supply, equipment production, and facility construction. It also has a vast downstream market – China’s huge petrochemical, machinery, The development of automobile, metallurgy and other industries has provided huge market demand for unsaturated polyester resin. According to the released “2022-2026 China Unsaturated Polyester Resin Industry Market Monitoring and Future Development Prospects Research Report“, China’s annual production capacity of unsaturated polyester resin exceeds 6.2 million tons, and its output exceeds 3.5 million tons. China’s unsaturated polyester resin has a certain degree of regional aggregation. The unsaturated polyester resin industry in Shandong, Fujian and Guangdong has stronger industrial chain advantages. The dominant position of Jiangsu’s unsaturated polyester resin industry is being challenged. In addition, China’s unsaturated polyester resin industry shows obvious characteristics of scale. The production capacity of a single enterprise is more than 100,000 tons, the production capacity of most enterprises is 200,000 tons, and the production capacity of a few enterprises has reached 300,000 tons. The production capacity of small and medium-sized enterprises is fiercely The advantages gradually weakened in the market competition.

In recent years, China has strengthened the adjustment of its industrial structure, coupled with the tightening of production safety and environmental protection policies, the chemical industry has been greatly affected – the adjustment of industrial structure has forced the elimination of some backward production capacities, while the tightening of production safety and environmental protection policies and the related supervision efforts have The increase has prompted chemical companies to increase their investment in new processes, new technologies, and new equipment, which has raised the operating costs of the chemical industry to a certain extent and also raised the entry threshold for the chemical industry. Against this background, the unsaturated polyester resin industry is actively building a product standard system, promoting the market to develop toward standardization and standardization, and promoting the upgrading of product structure and the adjustment of industry structure. China’s unsaturated polyester resin industry has gradually entered a healthy and sustainable development stage.

Analysts believe that China is a major economic country in the industrialization stage, and the market demand for unsaturated polyester resin as a basic chemical material is still There is great development potential. The adjusted unsaturated polyester resin industry will have strong strength in terms of technical strength, product layout, market development, etc., and will also have more development opportunities.
