Saturated polyester resin has wide application fields and broad room for future industry development.

Polyester resin refers to the general name of polymer compounds formed by the condensation of binary organic acids and polyols, including saturated polyester resin and unsaturated polyester resin. Saturated polyester resin, also known as oil-free alkyd resin, refers to a type of polymer compound produced by the reaction of different polybasic acids and polyols. According to different structures, saturated polyester resin can be divided into linear polyester resin and benzene ring polyester resin; according to different components, saturated polyester resin can be divided into hybrid saturated polyester resin and pure saturated polyester resin.

Saturated polyester resin has good moldability, fluidity, processability, weather resistance, corrosion resistance, chemical stability and other characteristics. It can be used to produce coatings, inks, adhesives, insulation materials and other products. End application fields include construction, Automobiles, ships, electronics, industry, electric power, aerospace, etc. Specifically, coating products produced using saturated polyester resin have the advantages of good gloss, strong weather resistance, and strong adhesion, and can be used in production scenarios such as automobile and ship coatings; insulation materials produced using saturated polyester resin have the characteristics of fire protection, With the advantages of corrosion resistance, heat resistance, and good insulation performance, it can be used in production scenarios such as power cable protective sleeves, cable protective tubes, and cable branches.

According to the“China Saturated Polyester Resin Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center It shows that saturated polyester resin has a wide range of application fields. With the rapid development of the application market, its market size has continued to expand. The global saturated polyester resin market size will reach US$4.57 billion in 2022, a year-on-year growth of 6.1%. From the production side, the global saturated polyester resin market is mainly in the hands of international companies that started earlier and have higher technical levels. Major companies include South Korea’s SK Chemical, Germany’s Synthopol, Japan’s Hitachi Chem, and the United States’ Nuplex.

my country’s research and development of saturated polyester resin began in the late 1950s. In the early days, it was mainly based on the introduction of foreign advanced technology and equipment. Later, with the rapid development of the domestic chemical industry, domestic saturated polyester resin has made great progress, and a number of products have appeared. Leading companies with advantages in technology, R&D, and scale, such as Guanghua Co., Ltd., Shangwei New Materials, Yongyue Technology, Yinyang Resin, Fenglin New Materials, Xiangrong New Materials, etc. However, domestic enterprises still have a large gap compared with leading foreign enterprises in terms of technology, product performance, R&D strength, etc. In the future, local enterprises will need to continuously improve their technical level.

Industry analysts said that saturated polyester resin is a type of high-performance composite material that is currently used in construction, electric power, automobiles, and ships. Achieve wide application in other fields. At the same time, saturated polyester resin is also a type of green and environmentally friendly material. As the green development trend of the domestic chemical industry continues to rise, the industry faces less environmental pressure and there is still huge room for development in the future.
