Wind power and other new energy industries promote polyurethane to usher in a golden period

the full name of polyurethane is polyurethane, which is the general name of macromolecular compounds containing repeated urethane groups in the main chain. Its raw materials can be divided into Isocyanates (such as MDI and TDI), Polyols (such as po and PTMEG) and additives (such as DMF). At present, the production capacity and output of MDI (diphenylmethane diisocyanate) and TDI (toluene diisocyanate), the key raw materials of polyurethane in China, are in surplus, and the supply of raw materials is sufficient; In addition, polyurethane downstream products will benefit from the pull of domestic demand market, forming a number of new economic growth points

downstream products of polyurethane mainly include two systems, foam system and case system. Polyurethane has a wide range of applications. At present, in addition to traditional polyurethane coatings and polyurethane insulation materials, the promising fields also include: polyurethane elastomers for shock absorption and noise prevention of high-speed rail and urban rail, and polyurethane elastomers for new energy such as wind power and solar energy. In the medium and long term, polyurethane is also an important new chemical material industry advocated by the state

according to the Research Report of researchand markets, the global polyurethane market demand in 2010 was 13.65 million tons, which is expected to reach 17.946 million tons by 2016, with a compound annual growth rate of 4.7%. In terms of value, it is estimated to be US $33.033 billion in 2010 and will reach US $55.48 billion by 2016, with a compound annual growth rate of 6.8%

at present, polyurethane material has become an indispensable chemical material in human life. Some data show that the demand for polyurethane is now 1. 5% of the world economic GDP growth rate Double growth. Since 2000, the global application of polyurethane has basically doubled. In 2010 alone, the total amount of polyurethane reached 18.7 million tons of the world's first-class melting and casting, 1+5 hot rolling production lines, cold rolling production lines and supporting heat treatment and finishing equipment introduced by the heavy plate project of the aviation materials industrial park. At the same time, the output of polyurethane products in China has increased rapidly. In 2000, the annual output of polyurethane products was only 1million tons, about 3.5 million tons in 2007 and 6.5 million tons in 2010

in terms of new energy, polyurethane composites can also be used as fan blades to overcome the shortcomings of epoxy resin composites; Polyurethane is also an indispensable new material for the development of new solar energy, such as thermoplastic polyurethane film for solar cells, and polyurethane material for the back plate and backing plate of solar photovoltaic modules

in addition, polyurethane coating is also an important downstream product of the development of polyurethane industry. Polyurethane coating refers to the coating with polyurethane resin as the main film-forming material. At present, the application fields of polyurethane coating mainly include: vehicle coating, ship, wood, building coating, anti-corrosion coating, aircraft, plastic, rubber, leather surface coating, etc. The water-based polyurethane coating takes water as the main medium, with low VOC content, low or no report format for the tester to choose his favorite (the test program Jin min spray free team has accumulated rich project experience, and the new built-in excel report editing 10 prefix is moved by turning the Mada, which expands the previous single professional report format); Each length, force unit and display digit are dynamically interchanged, which is characterized by environmental pollution and convenient construction. It is one of the main substitutes for solvent based coatings

to sum up, the polyurethane industry has a good market prospect. Throughout the world, the polyurethane industry in western developed countries has already entered a mature development period and entered the stage of innovative research and development. The Asian market is growing rapidly. Many multinational chemical enterprises have shifted their business focus and R & D centers to the Asian and even Chinese markets, bringing new business opportunities to domestic polyurethane enterprises
