Research in the field of polyurethane for vehicles

with the development of the automotive industry for more than 100 years, polyurethane has been more and more widely used in modern vehicles. The orders of China's plastic extruder enterprises have rebounded significantly. Relevant statistical data show that in 1998, the global automobile output was 52million, and the global automobile manufacturing industry used 520000 tons of polyurethane. In 2005, the global automobile output was 66million, and the use of polyurethane was 1.2 million tons. The growth rate of polyurethane usage has far exceeded that of automobile output

relevant experts pointed out that relatively speaking, the proportion of plastic used in high-end cars in the whole vehicle is higher than that of medium and low-end cars, that is, with the improvement of car grade, higher requirements are put forward for its comfort and other performance, so more plastic is needed. Polyurethane is the only composite material that can be applied in the six fields of plastic, rubber, fiber, coating, adhesive and functional polymer

its application in automobile is mainly divided into 13 categories according to polyurethane varieties: soft foam, molded foam, semi-rigid foam, hard foam, self skinning foam, reaction injection molding (RIM) microporous elastomer, reinforced rim microporous elastomer, pouring elastomer, TPU, composite structural materials, synthetic leather spandex, bonding and sealing materials, and coatings

relevant institutions predict that by 2010, the consumption of polyurethane in China's automotive industry will reach 15600 tons

the development of China's automotive industry will directly determine the future trend of the domestic automotive polyurethane industry. At the 2009 automotive interior industry chain forum held in Nanjing, the ancient capital, on September 10, Zhang Xin, an automotive industry analyst with Guotai Junan automobile computer, who can calculate and display the impact absorption energy, impact toughness, pendulum angle and experimental average value, will summarize the development of the automotive industry in the first half of 2009 and prospect the future trend. From this, we can also see the future development momentum of the domestic automotive polyurethane market
