Polyurethane adhesives, due to their excellent bonding performance, flexibility and fatigue resistance, have become an indispensable and important part of China's adhesive industry. At present, its development presents the following several notable characteristics:
Current development status
1.The industrial scale continues to expand: China has become the world's largest producer and consumer of polyurethane adhesives. Driven by the demand in traditional and emerging fields such as construction, packaging, shoemaking, automobiles, new energy, and electronic appliances, both production and consumption have been steadily increasing.
2.The application fields are constantly expanding: In addition to maintaining stable applications in traditional fields such as clothing, footwear, and furniture, its application in high-tech fields such as new energy vehicles (battery pack packaging, structural bonding), wind power generation (blade bonding), and electronic appliances (screen bonding, component fixation) is rapidly expanding, becoming the main driving force for market growth.
3.Environmental protection and high performance have become the themes: With increasingly strict environmental regulations, water-based, solvent-free, bio-based and other environmentally friendly polyurethane adhesives have become the focus of research and development and promotion. Meanwhile, the market has put forward higher requirements for the high-performance indicators of products such as high-temperature resistance, high bonding strength, and rapid curing.
4.Enhanced technological autonomy: Domestic R&D investment has continued to increase, achieving breakthroughs in core raw materials, formula processes and application technologies, gradually narrowing the gap with international advanced levels. Some products have already achieved import substitution.
Future development direction
1.Greening and sustainable development: The core direction of future development is greening. The technology of water-based and solvent-free products will become more mature, and their market share will further expand. At the same time, developing polyurethane adhesives based on renewable resources (such as bio-based polyols), as well as enhancing the recyclability and degradability of the products, will be long-term tasks.
2.High-end and functionalization: It is an inevitable trend to develop high-value-added products with special functions (such as electrical conductivity, thermal conductivity, flame retardancy, and optical transparency) for cutting-edge fields like aerospace, high-end electronics, and precision medical care. Meeting the usage requirements under extreme working conditions is the high ground of technological competition.
3.Intelligence and Customization: With the advancement of Industry 4.0 and intelligent manufacturing, the demand for intelligent adhesives that can adapt to automated production lines and have specific curing curves or inductive response characteristics will rise. At the same time, the ability to provide customized solutions for specific customers and scenarios will become the core competitiveness of enterprises.
4.Collaborative innovation in the industrial chain: The stable supply and performance improvement of upstream raw materials (such as special isocyanates and polyols), as well as close cooperation with downstream application industries, will jointly promote the technological progress and application innovation of polyurethane adhesives, which will be the key to the healthy development of the industry.
In conclusion, the Chinese
Polyurethane Adhesive industry is moving from scale expansion to quality improvement and green transformation. In the future, driven by both technological innovation and sustainable development, it will move towards a higher added value development stage.
