Polyurethane is important chemical new material, because of its function outstanding, utility is changeful, be known as “ the 5th big plastic ” . The course work up that industry of our country polyurethane accompanies Party building 100 years expands. Now, from furniture, dress, to traffic, building, build to aerospace, national defence again, the polyurethane material that nowhere is absent represented modernization to learn innovation level of industry not only, what also become our country to build manufacturing industry power is important prop up.

Industry of our country polyurethane only then at going up century 50 time end at the beginning of 60 generation, from production polyurethane raw material starts. 1958, dalian dye factory takes the lead in developing successful toluene ester of 2 different cyanic acid (TDI) , produce unit of 500 tons of production at proposing year after year 1968, created development condition for industry of our country polyurethane. Subsequently, the unit such as institute of Jiangsu province chemical industry is developed early or late piece get together ether PU is soft qualitative expanded plastics, mix refine PU elastomer (the product such as waterproof of coating of MPU) , polyurethane, polyurethane. 1976, jiangsu saves chemical hall to organize Jiangsu to save the unit such as chemical institute to undertake the technology of polyurethane runway glue tackles key problem, began to be in 1978 large area of place of domestic each sort sports popularizes application. After reforming and opening, our country begins to introduce abroad's advanced TDI to produce technology and device. 1983, former light the Ministry of Works in feudal China is cast in Shandong Yantai build produce per year firedamp of 10 thousand tons of 2 phenyl ester of 2 different cyanic acid (MDI) and TDI project put into production. 20 centuries after 80 time, our country begins to introduce abroad's advanced polyurethane raw material and goods production technology, equipment, orgnaization of domestic each scientific research and enterprise also begin development to react inject shapes, tall spring back is cold ripe dissolve bubble, polymer multivariate the new technology of a series of goods such as MDI of mellow, modified and special type raw material. The car that academy of matutinal chemical industry develops is used from dashboard of elastomer of dashboard of knot skin steering wheel, inserts, small hole, Leng Gu to change bubble of tall spring back, suck can fight strong model bumper imitate wait for 5 kinds of goods, fill home is blank. Go up century after 90 time, last as our country economy high speed develops, polyurethane serves as new-style muti_function high polymer material, wider and wider application receives in the domain such as traffic, home appliance, furniture, metallurgy. The rapid growth of demand also spurred the development of polyurethane industry further, epispastic small company develops box type of flexible qualitative foam flourishingly, what freezer produces base is automatic and pouring hard bubble of plank of product line of layer of hard bubble heat insulation, with filling is pouring the gross such as product line of soft bubble of product line of product line, soft bubble of continuous method chunk, moulding about a hundred, the manufacturer such as sticky agent of large polyurethane coating, glue also has many 10. Enter 21 centuries, through ten years tackle key problem research and experience are accumulated, through be being absorbed to introducing the assimilation of technical unit, our country mastered polyurethane basically the manufacturing technology of main raw material. As the rapid development of industry of ark of our country freezer, ice, furniture, the application of polyurethane material rises abruptly quickly, industry of our country polyurethane enters flying development phase, one of fast fields develop in making trade of our country chemical industry. With Yantai 10 thousand China for the delegate, the polyurethane production company of our country is in the domain such as level of scale of production, line of the products, technology begins comprehensive breakthrough, arena of international of body of bibcock enterprise ascend, the industry was formed cross a country to turn look forward to, large state-owend enterprise and civilian battalion company the situation of 3 sufficient tripartite balance of forces. During 935 ” of “ , the assimilation of industry of polyurethane raw material through nearly 20 years, absorb and create again, MDI produces technology and productivity to live banner standard, get together ether is multivariate mellow production technology and ability of scientific research innovation promote ceaselessly, high-end product is ceaseless emerge in large numbers, with abroad the difference of advanced level narrows ceaselessly. Consumption of product of our country polyurethane made an appointment with 11.5 million tons 2019 (contain solvent) , raw material exports year after year to increase, it is big polyurethane production and consumptive area, the market matures further, the technology that the industry begins to enter high quality to develop promotes period. Current, main raw material produces polyurethane all can produce more than can 1/3, become big polyurethane raw material and goods production base, also be to go up the area with polyurethane application whole field, industry raw material and goods production, consumption grows continuously, industrial structure is optimized continuously. Production value of polyurethane raw material 60 billion yuan, product production value 320 billion yuan, produced complete the cold storage container of 95% , toy of 70% , shoe of 60% . Current, polyurethane industry was stridden lead in order to innovate, the new level that green development gives priority to a problem. At present the crop of downstream product all resides the polyurethane such as black silk ribbon of our country building materials, ammonia, synthetic leather and car. Popularizing coating of ability in swimming, executive building energetically car of new energy resources of energy-saving new policy, development, also bring tremendous market opportunity for polyurethane industry. The target of ” of “ double carbon that our country raises, will urge a construction energy-saving develop quickly with clean energy industry, wait for sticky agent of polyurethane insulation material, coating, composite material, glue, elastomer bring new development opportunity. This year in April, announce to accept " Jijiali amendment " , strengthen hydrogenous fluorine carbide (the blame such as HFCs) canal of gas of carbon dioxide greenhouse accuses. Our country is big HFCs production, use country, among them HFCs vesicant is used extensively in polyurethane foam industry, cut down working existence to challenge. At present filling day new material, carry on is promoted China achieve, Jiangsu beauty thinks of the company such as heart to replace the job in the light of ODS of polyurethane industry vesicant, the research and development that increased the auxiliary such as new-style vesicant and the agent of divide evenly bubble that cooperate to it, activator upgrades, contribute force to improve atmosphere environment.
