Discussion on the worldwide situation of polyurethane adhesive

Polyurethane Adhesive, as a high-performance synthetic adhesive, occupies a decisive position in the world. Its unique chemical structure endows it with excellent properties, including high bonding strength, excellent impact resistance, wear resistance, good flexibility and low temperature resistance. These characteristics enable it to bond a variety of materials, such as metal, plastic, wood, fabric and leather, so it has been widely used in many industrial fields.

 

From the perspective of global market, the demand for polyurethane adhesives continues to grow, and its driving force mainly comes from key industries such as automobile, construction, packaging, shoemaking and electronics. In the automobile industry, it is used to bond interior trim, window glass, structural components and lightweight materials. With the development of new energy vehicles, the demand for new applications such as battery pack packaging is also rising. In the field of architecture, it is used as a high-performance sealant and structural adhesive for sealing and bonding curtain walls, interior decoration and energy-saving doors and windows. Flexible packaging industry is another big application market, and solvent-free polyurethane laminating adhesive is gradually replacing traditional solvent-based products and becoming the development trend of the industry because of its environmental advantages.

 

At present, the development of polyurethane adhesive technology in the world presents obvious environmental protection and high performance orientation. Waterborne polyurethane adhesives, solvent-free polyurethane adhesives and bio-based polyurethane adhesives are the focus of research and development, aiming at reducing the emission of volatile organic compounds and meeting the increasingly stringent environmental regulations. At the same time, the development of special polyurethane adhesives for specific application scenarios (such as high temperature resistance and super bonding) is also deepening.

 

In terms of geographical distribution, Asia-Pacific region is the largest polyurethane adhesive market in the world, which benefits from the booming manufacturing industry and huge consumer market in this region, especially in East and Southeast Asian countries. The markets in North America and Europe are more mature, with relatively stable growth, but the demand for high-end and environment-friendly products is stronger.

 

Polyurethane adhesive has a broad market prospect in the world, and its future development will closely focus on sustainability, functionalization and adaptation to the challenges of new materials, and continue to promote technological innovation and industrial
