Consumption structure of polyurethane adhesives

November 13, 2024

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.

According to the data of the China Association of Automobile Manufacturers, the production and sales of automobiles in 2022 will be 27.021 million and 26.864 million, respectively, an increase of 3.4% and 2.1%. The use of polyurethane adhesives for windshields is also growing rapidly. Of course, the body, interior, instrumentation, engine and other components will also be used in the product, in view of the huge car ownership, maintenance market consumption can not be underestimated.

In recent years, polyurethane adhesives have played an increasingly important role in the bonding of aerospace equipment, cultural relics protection and restoration, military industry, stationery, medical and health care, etc., due to their excellent bonding characteristics. Polyurethane adhesives are widely used in various fields for their excellent properties, and have gradually become an important synthetic material in human life.
