application of composite polyurethane adhesive
Composite polyurethane adhesive is mainly used in packaging, printing, leather, textile and footwear, transportation, electronic appliances, furniture and building materials, safety protection, new energy, tobacco etc..
In four, the composite polyurethane adhesive industry
1. Since the reform and opening up, China’s composite polyurethane adhesive industry has been sustained, rapid and stable development, and has formed a certain scale of production, but from the industry point of view, medium and small scale composite polyurethane adhesive manufacturers in the industry is still the main body. According to incomplete statistics, the composite polyurethane adhesive production enterprises in our country as many as hundreds, most are for small and medium enterprises, distributed in 28 provinces and autonomous regions nationwide, with annual sales income of 50 million yuan or more and with independent technology based enterprises less than 10; and the majority of small and medium-sized enterprises production technology and management level is low, output is little and the product grade is low, difficult to deal with the modernization of production and the challenges of market competition.

The composite polyurethane adhesive as the high-end products in the industry, though started late, R & D investment is relatively small and historical reasons, domestic production enterprises in a few products on the technical level is unable to compete with international companies, but benefit from the application of new materials in the field of domestic development and the domestic economy 10 years of rapid development, still to maintain a strong momentum of development, production and sales of nearly 10 years of rapid growth, the average growth rate reached 20%.
In 2009 the domestic industrial added value growth of 11% in 2008 under the environment of China’s application in the field of plastic flexible packaging composite polyurethane adhesive production reached 215 thousand tons, still achieved a high growth rate of 26.5%, while at the same time, its sales accounted for only 5.5% of all kinds of adhesive products of total sales, but sales are the total adhesive total sales of more than 8%, has played an important role in the adhesive industry.

Five, the main industry development trend
At present, the composite polyurethane adhesive industry development presents the following trends
The expansion of application fields
As a high-end composite polyurethane adhesive adhesive, besides getting widely used in food, medicine, daily chemicals, precision instruments, instrument and electronic device and other traditional packaging field, in oil printing, household appliances, building materials, transportation, energy, security and other fields have begun to have a broad application.
The increase of industrial concentration
In recent years, the increasing users of composite polyurethane adhesive product quality, performance and environmental requirements, the brand awareness of enterprises in the industry continue to strengthen the market competition is becoming increasingly fierce. The overall trend of industry scale, intensive development, and constantly improve the industry concentration; the rapid expansion of R & D strength, a high level of technology enterprises.

The professional development
With the continuous innovation of domestic demand is gradually increasing, composite polyurethane adhesive application, according to customer requirements for product performance tailored special composite polyurethane adhesive will become the future development trend of high-end adhesive, it will put forward higher requirements of research ability and professional level of composite polyurethane adhesive production enterprises.
The import substitution trend
In recent years, in the part of the composite polyurethane adhesive products, domestic enterprises have made great progress in technology, this part gradually to replace imported products, and in the West shows giant to compete, and downstream customers to reduce their costs from the point of view, there is a strong demand to replace imported products, which also stimulated the domestic products R & D and production.
Six, the industry market competition pattern
Small and medium-sized enterprises of our country composite polyurethane adhesive industry in large quantity, widely dispersed, these enterprises in the technical level is low the product industry, products with lower profit margins in the industry, so the bottom of the Pyramid, have a small number of high-end composite polyurethane adhesive with independent intellectual property rights of the domestic enterprises, the main production technology content and higher margin products in the upper part, the industry in Pyramid; and the international giant by virtue of its strong R & D capability and brand advantages, through the establishment of a joint venture or production base in China to reduce the production cost, in the most high-end products in the market have obvious competitive advantage to achieve monopoly, the rate of technology research and development, at the top of Pyramid.
Composite polyurethane adhesive as high-end products in the industry, due to the enterprise research and development ability, technical level, sales channels and other requirements are very high, our long-term monopolized by Germany Henkel company, Dow Corning company, 3M company in the United States and other international giants, many domestic industries for composite polyurethane adhesives are dependent on imports or joint venture products. Since the last century since 90s, domestic enterprises, research institutes and other units gradually began to enter the field of product independent research and development, after many years of accumulated technology, gradually in the composite polyurethane adhesive products have independent intellectual development as the goal, to replace imports.
The field of plastic soft packaging is one of the most important applications of composite polyurethane adhesive, plastic soft packaging composite polyurethane adhesive after years of development, has its proportion of composite polyurethane adhesive production and sales reached more than 50%, with more mature markets. In 2009, China’s production of plastic flexible packaging composite polyurethane adhesive reached 215 thousand tons. At present, the domestic soft plastic packaging composite polyurethane adhesives market formed the following pattern: multinational companies most high-end products air break, domestic enterprises to improve concentration, attention segments, expand the high-end market share constantly, gradually realize the import substitution products. “Plastic composite flexible packaging adhesives Market Research” a “Chinese packaging industry”
