The market size of unsaturated polyester resin exceeds 60 billion, with phthalic acid type being the main type


Unsaturated polyester resin is generally a linear polymer compound 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. Unsaturated polyester resin has good corrosion resistance, resistance to acids, alkalis, salts, most organic solvents, seawater and other substances, and is widely used in petrochemical, pharmaceutical, printing and dyeing, electroplating, electrolysis, smelting, light industry and many other fields.

According to different structures, unsaturated polyester resin can be divided into phthalic acid type, isophthalic acid type (isophthalic acid type for short), bisphenol A type and vinyl ester type, halogenated unsaturated polyester resin and other types. Among them, phthalic acid-type unsaturated polyester resin has high flexibility and good tensile strength. It is the most popular resin in the shipbuilding industry and is also used in adhesives, castings, composite materials, packaging, floor materials, condensation materials, etc. The preferred resin type in many fields such as adhesive coatings, filler pastes, pigment pastes, polymer concrete, putty and tools, etc. Therefore, phthalic acid type is currently the most commonly used unsaturated polyester resin, accounting for the largest share of unsaturated polyester resins. maximum.

Industrial Research Center released “China’s 2021-2025 The “Saturated Polyester Resin Industry Market Monitoring and Future Development Prospects Research Report” shows that in 2020, affected by the new coronavirus pneumonia epidemic, global industry, tourism, steel, petrochemical and other industries will suffer to varying degrees. Affected, but unsaturated polyester resin has still achieved market size growth with its excellent performance. The global unsaturated polyester resin market size has exceeded 60 billion yuan in 2020, of which China is the world’s largest unsaturated polyester resin consumer market. , and developed countries such as Europe and the United States also have a relatively large demand for unsaturated polyester resin, and they are also the world’s major demand markets for unsaturated polyester resin.

At present, most of China’s unsaturated polyester resin industry consists of small and medium-sized enterprises, and the technical level lags behind developed countries and regions such as Europe and the United States. Unsaturated polyester resin products are mainly used in the production of fiberglass composite materials, coatings, artificial stone and other products. In the future, with the development of urban construction, industrial development and energy structure adjustment in my country, the downstream application industry of unsaturated polyester resin will be further developed. As one of the three major types of thermosetting resins in my country (epoxy resin, phenolic resin, unsaturated resin ), the fastest growing, most widely used and most produced variety, the demand for unsaturated polyester resin will further increase, and the industry still has good development prospects.

In foreign markets, the use of lighter-weight FRP (fiber-reinforced composite plastics) in pipes, storage tanks, pressure vessels and cylinders has increased significantly in recent years, driving the growth of foreign demand for unsaturated polyester resins. In the future, as new developing countries and regions such as India, Brazil and the Middle East continue to expand their investment scale in the field of infrastructure construction, and developed countries such as Europe, the United States and Japan continue to adjust their economic and energy structures, foreign demand for unsaturated polyester resin will also increase. will continue to grow. It is expected that the global unsaturated polyester resin market size will exceed 80 billion yuan in 2025, and the industry market size has large room for growth.
