Aromatic polyester polyols have a wide range of applications and currently the market penetration rate in my country is low.

There are many types of polyester polyols. According to whether they contain benzene rings, they can be divided into aromatic polyester polyols and aliphatic polyols. Aromatic polyester polyols refer to polyester polyols obtained by polymerizing phthalic anhydride and diols or triols. Aromatic polyester polyol appears as a light yellow to brown-red transparent liquid with a slightly aromatic odor. It has the advantages of good processing performance, good heat resistance, and good flame retardancy. It can be used to manufacture rigid foam plastics, non-foam polyurethane, etc. Products are widely used in building materials, coatings, elastomers, adhesives and other fields.

The batch method is the main preparation method for aromatic polyester polyols. This method uses acid and alcohol as the main raw materials. After heating and stirring, nitrogen is introduced, and then the finished product is obtained through processes such as dealcoholization and cooling. The batch method is suitable for large-scale production, but it has disadvantages such as poor quality of finished products, low utilization of raw materials, and easy cause of environmental pollution. In the future, as research intensity continues to increase, the technical level of aromatic polyester polyols in my country will improve.

Aromatic polyester polyols have a wide range of applications, including building materials, coatings, elastomers, adhesives, etc. In the field of building materials, aromatic polyester polyols can be used to produce sandwich foam boards; in the field of coatings, aromatic polyester polyol coatings can be used for surface spraying of wooden furniture and metal decorations. With the growth of downstream demand, the development space of the aromatic polyester polyol industry continues to expand. According to the “2023-2028 China Aromatic Polyester Polyol Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center 》 shows that the global aromatic polyester polyol market size will reach US$1.89 billion in 2022, a year-on-year increase of 10.2%.

The global aromatic polyester polyol market is mainly concentrated in European and American countries. The United States Stibbing Company (SCL), the United States Invista (INVISTA), and the United States Huntsman Group (Huntsman) are world-renowned producers of aromatic polyester polyols. business. Huntsman Group is the world’s largest manufacturer of aromatic polyester polyols. Its star product TEROL has adhesion, hydrolysis resistance and heat resistance and is widely used in many fields such as hot melt adhesives and building materials.

The market penetration rate of aromatic polyester polyols in my country is low. Wanhua Chemical, Huafeng Chemical, Lianchuang Co., Ltd., Kanos Technology, Nanguang Chemical, Kangsold Chemical, Ruinuo Chemical, etc. are the leading aromatic polyester polyols in my country. major producers. Wanhua Chemical is a representative enterprise of aromatic polyester polyols in my country. In recent years, the company has focused on the research and development of high-end new chemical materials and has now achieved industrialized production of aromatic polyester polyols.

Industry analysts said that as a segmented product of polyester polyols, aromatic polyester polyols are widely used in rigid foam plastics and non-ferrous plastics. Foam polyurethane and other products are widely used in the production process. Compared with overseas developed countries, my country’s aromatic polyester polyol industry started late and its product market penetration rate is low. In the future, as the technical level of local enterprises continues to improve, the development space of my country’s aromatic polyester polyol industry will further expand.
