The application level of polyurethane in the automotive industry needs to be improved.

recently, BASF, the world's largest producer of chemical raw materials, completed and put into operation an integrated polyurethane production base in Pudong, Shanghai. This is a research and development center integrating the development of polyurethane technology in the Asia Pacific region, which can effectively solve the energy combination material device and the production of thermoplastic polyurethane

users in the domestic automotive industry have an important multinational supplier in the supply of high-quality raw materials and the development and production of high-quality automotive interior and exterior trim assemblies and parts, which will have a positive impact on improving the application level of high-quality polyurethane materials in the domestic automotive industry

Dr. Federman, executive director of polymer of BASF, said that China is an important consumer market of polyurethane in the world. In 2006, the global TPE demand reached about 2.15 million tons. At present, TPS accounts for about 44%, TPO 31%, TPU 9.5% and TPEE 6.5% of the TPE consumption structure. Styrene TPE still ranks first in consumption. As TPO enters the automobile to replace traditional thermosetting rubber and PVC materials, the market share of TPO will continue to expand

according to relevant experts, with the explosive growth of China's automobile market in recent years, the application of TPU will increase rapidly, among which the use of hextow hm63 for any high strength and high stiffness is an ideal material, accounting for more than 75% of the total output, and the consumption in 2006 reached about 370000 tons. China has become one of the countries with the fastest growth of TPU demand in the world, especially the automobile centered application market will maintain an average annual high-speed growth of 10%. In 2006, a forum on the application of polyurethane in China's automotive industry was held in China, which shows that with the rapid development of the automotive industry in recent years, polyurethane products are increasingly used in the automotive industry. At present, the Ningbo Institute of materials technology and engineering of the Chinese Academy of polyurethane and the Canadian composite Innovation Center held the first China Canada International Symposium on green composite materials at the International Education Exchange Building of Beijing University of technology on May 9 (1) 0, 2011. The products account for 20% of the consumption of automotive plastics. Polyurethane products are used for car seats, as well as the previously mentioned sound insulation materials, instrument panels, sun visors, door panels, ceiling linings and other parts

some domestic insiders said that from the perspective of reuse, lightweight and high performance, TPE will have a broad market in the future, so it is necessary to accelerate the process of TPE localization required by China's automotive industry. Polyurethane products are welcomed by automotive interior designers, engineers, raw material procurement experts and acoustic engineers. Polyurethane composite materials have brought value-added services to modern car products and improved the quality of car interior. At present, high-performance microporous polyurethane elastomer has become an important raw material for automotive buffer systems, engine support pads, motorcycle buffer blocks and industrial buffer blocks

in the modern automobile manufacturing industry, the upgrading of non-metallic materials such as interior trim and shock absorption has developed to a new stage. Industry insiders introduced such a set of data. The application proportion of polyurethane in the automotive industry in Europe, the United States and Japan reached 40% - 50%, while the utilization rate of polyurethane materials in China's automotive industry was less than 20%, which was still at a low level. However, subject to the pressure of price reduction in the domestic automotive market, it will take time for the application of polyurethane materials produced in China's automotive industry to reach the same level abroad

thermoplastic polyurethane elastomer can greatly reduce the weight and energy consumption of vehicles by replacing traditional metal parts and traditional thermoplastic parts. Polyethylene can be used to manufacture fuel tanks, fenders, steering wheels, various liquid storage tanks, interior trims and linings. Compared with the metal fuel tank, the plastic fuel tank blow molded with high molecular density polyethylene has light weight, good corrosion resistance and full use of space. In addition, the plastic fuel tank can be formed at one time to reduce costs and simplify the process. Many domestic cars have adopted multi-layer composite polyethylene plastic fuel tanks, such as Shanghai General Motors Buick series cars and station wagons, FAW Volkswagen Sagitar and Shanghai Volkswagen Passat B5 cars

with polyurethane as the body component material, manufacturers adopt new technologies to reduce production costs and design streamlined and modern cars. In terms of physical properties, polyurethane is significantly different from steel materials in that it can absorb impact force well during collision deformation; Corrosion resistance, heat insulation, sound insulation, easy to form, color and repair; The production cost is low

thermoplastic polyurethane elastomer has excellent bearing capacity, energy absorption, cutting resistance, wear resistance, low-temperature impact, oil resistance, solvent resistance, weather aging resistance, etc
