Future development trend of adhesives

In the next five years, my country will focus on the development of environmentally friendly and energy-saving adhesives, and will also vigorously research and develop new adhesive products with high technology content, high added value and high performance. Mainly including: water-based polyurethane adhesives, water-based chloroprene rubber adhesives, high-performance and high-quality pressure-sensitive adhesives and products, VAE (vinyl acetate-ethylene) emulsions, EVA (ethylene-vinyl acetate) resins, SIS (styrene-isoprene-styrene) resins, etc.

Water-based polyurethane adhesives and water-based chloroprene rubber adhesives are environmentally friendly products. In recent years, they have developed rapidly in industrially developed countries such as Europe, the United States, and Japan, and have been widely used in construction, furniture, shoemaking and other industries, while this technology is still blank in my country. Therefore, in the next five years, my country will not only increase the research and development of these two types of adhesives, but also plan to introduce advanced foreign production technologies and processes to build a 5,000 tons/year water-based polyurethane adhesive production unit to meet part of the domestic market demand.

In terms of high-performance and high-quality pressure-sensitive adhesives and products, my country plans to build a 5,000-ton/year high-performance, high-quality acrylic pressure-sensitive adhesive production unit and coating production line.

VAE emulsion is one of the excellent adhesives in water-based adhesives. In 2004, my country's VAE emulsion production was only 103,000 tons, far from meeting market demand. Therefore, my country plans to build another 100,000-ton/year production unit within 5 years.

Hot melt adhesive is an environmentally friendly adhesive. In 2004, my country's production was about 65,000 tons, and it is expected that the production will reach 160,000 tons in 2010. However, the main raw material for producing this adhesive, EVA resin, is currently entirely imported. Therefore, my country plans to build a 100,000-ton/year EVA resin production unit within 5 years to meet the development needs of hot melt adhesives.

SIS resin is an important raw material for the production of hot melt pressure-sensitive adhesives and other adhesives. At present, my country only has one production unit with an annual output of about 5,000 tons, which is far from meeting the domestic market demand in terms of quality and quantity. Therefore, in the next five years, my country plans to build a SIS resin production plant with an annual capacity of 20,000 to 30,000 tons.
