The development status and industry characteristics of polyurethane adhesives

1. The development status and industry characteristics of polyurethane adhesives

a. Development status of polyurethane adhesives

With the continuous advancement of urbanization, information technology and industrialization, domestic investment demand, consumption upgrading demand and ecological environment improvement demand have brought huge growth space for China's polyurethane adhesive market. The rapid development of China's polyurethane adhesive market is mainly related to the continuous development of the domestic economy, as well as the rapid growth of the automobile manufacturing, construction industry and other industries.

Under the background of the growing market in downstream traditional areas and emerging areas, it is expected that the market size of polyurethane adhesives in China will continue to maintain rapid growth in the next few years. According to the annual meeting of the China Adhesive and Adhesive Tape Industry Association, during the "14th Five-Year Plan" period, the development goal of China's adhesive industry is an average annual growth rate of 4.2%, an average annual sales growth rate of 4.3%, and strive to reach more than 40% of the industry's high value-added product output value by the end of 2025.

b. Polyurethane adhesive industry characteristics

In recent years, China's polyurethane adhesive industry has been slowed by the growth of consumer demand for construction-related adhesives, but thanks to the rapid development of domestic emerging industries such as new energy industry, the demand for such polyurethane adhesives has increased. However, with the gradual expansion of the production scale of polyurethane adhesive in China, while the production of polyurethane adhesive is facing the impact of national environmental protection and energy saving policies, it is necessary to improve the production line, and the production growth rate in the next five years may slow down to meet the national energy saving and consumption reduction requirements; In the future, with the stability of downstream traditional industries and the development of emerging industries such as new energy, the consumption demand for polyurethane adhesives will be greatly increased.

2. Polyurethane adhesive consumption structure

China's polyurethane adhesive application field is extremely wide, from building materials, shoe industry, packaging, automobiles and other traditional consumer areas to electronic appliances, automotive industry, aerospace, new energy fields and a series of emerging fields. With the slow growth of the real estate sector, the growth rate of rubber used in construction, home improvement, building materials, woodworking and home furnishing industries has slowed down; However, the amount of adhesive used in emerging fields such as new energy vehicles, power batteries, and new energy power generation has increased rapidly, which is the fast track for the development of polyurethane adhesives in the future.

In the application fields of polyurethane adhesives, the consumption proportion of the construction field is the highest, reaching more than 26%, followed by the packaging industry, accounting for 25.97%, and the proportion of automobiles and transportation, woodworking furniture fields ranges from 6-10%.

In the automotive and transportation fields, the most widely used polyurethane adhesives are mainly one-component wet curing polyurethane sealant for windshield assembly; Structural adhesives for bonding glass fiber reinforced plastics and sheet molding composites, two-component polyurethane adhesives for interior parts and waterborne polyurethane adhesives, etc. Automotive interior parts are also an area where the amount of adhesives is growing.
