Polyurethane potting glue (PU potting glue) can be used to produce electronic components. The process of localization in the Chinese market is accelerating.

Polyurethane potting glue, also known as PU potting glue and two-component polyurethane potting glue, refers to polyols using diols or diamines as chain extenders and oligomers such as polyethers, polyesters and polydiolefins. A potting glue made by polymerizing diisocyanate as raw material. Polyurethane potting glue has the advantages of good electrical insulation, good elasticity, low hardness, flame retardancy, corrosion resistance, and water resistance, and is widely used in the field of electronic components.

In March 2022, six departments including the Ministry of Industry and Information Technology jointly issued the “Guiding Opinions on Promoting High-Quality Development of the Petrochemical and Chemical Industry during the “14th Five-Year Plan””. The document clearly stated that the “three products” action should be implemented and vigorously develop electronic chemicals and high-end polyolefins. and other products. Benefiting from the support of national policies, the development trend of the polyurethane potting adhesive industry as an electronic chemical continues to improve.

According to the “2023-2028 China Polyurethane Potting Adhesive (PU Potting Adhesive) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center 》shows that polyurethane potting adhesive has excellent performance and can be used in the production process of electronic components. New energy vehicles, household appliances, electric bicycles, consumer electronics, power systems, etc. are its end markets. In the field of new energy vehicles, polyurethane potting glue can be used for potting power battery cells and potting inside automobile casings. my country is a major producer and consumer of new energy vehicles. Benefiting from the accelerated development of downstream industries, the market demand for polyurethane potting adhesives is increasingly strong.

Major global manufacturers of polyurethane potting compounds include Japan’s Shin-Etsu Chemical Industry Co., Ltd. (Shin-Etsu), Germany’s Henkel Loctite (LOCTITE), the United States’ EPIC Corporation (EPIC), the United States’ Dow Chemical Company (DOW), and Switzerland’s Sika Company (SIKA) etc. The main manufacturers of polyurethane potting adhesives in my country include Beijing Gaomeng New Materials Co., Ltd., Guangzhou Jitai Chemical Co., Ltd., Wuxi Huiqitai Electronic Materials Co., Ltd., Changzhou Xenqi New Materials Co., Ltd., Yantai Dongbang Polyurethane Co., Ltd., etc. .

In the early stages of industry development, my country’s polyurethane potting glue was highly dependent on imports due to factors such as high technical barriers. As the world’s largest supplier of polyurethane potting adhesives, Swiss Sika Company also occupies a dominant position in my country’s market. In recent years, Chinese companies have continued to increase investment in research and development, driving the localization process of the polyurethane potting adhesive market to continue to accelerate. The polyurethane thermally conductive potting glue independently developed by Gaomeng New Materials has been widely used in the field of new energy vehicle power batteries.

Industry analysts said that as an electronic chemical, polyurethane potting glue has excellent performance and is widely used in many fields. Compared with overseas developed countries, my country’s polyurethane potting adhesive industry started late and its demand is highly dependent on imports. In the future, driven by national policy support and the technological innovation of local enterprises, my country’s polyurethane potting adhesive industry will gradually develop in a high-quality direction.
