As the income level of Chinese residents continues to increase, the demand for automobiles is gradually increasing. According to the statistics of the National Bureau of Statistics website, in 2014, China's automobile production was 23.889 million, and the average annual compound growth rate in 2006-2014 was 16.02%. Lightweight and environmental protection are the main directions for the development of automotive materials. Reducing the weight of the car itself is recognized as one of the effective measures to reduce vehicle emissions and improve combustion efficiency. Plastics are one of the most important automotive lightweight materials, which can significantly reduce the weight of the car while significantly reducing the cost of production for car manufacturers. In recent years, with the continuous development of plastic modification technology, more and more automotive parts have reached the design requirements of plastic materials. The use of plastics in automobiles has also expanded from traditional decorative parts to functional parts. At present, the consumption of plastics for medium and high-class cars in China is about 100-130kg/car, far behind the highest level of automotive plastics in developed countries, 200-300kg/car, and the technical level of 20% of the total vehicle mass. With the continuous improvement of the light weight of automobiles, the proportion of automotive plastics at home and abroad and its proportion of vehicle quality will further increase. Therefore, the application space of plastics and masterbatch in China in the automobile industry is very broad.
