Study on new pvc materials

At present, the total annual demand for modified plastics in China is about 5 million tons, accounting for about 10% of the total plastic consumption, which is far below the world average. There is still a big gap between China's per capita plastic consumption and that of developed countries in the world. In order to realize the rapid and stable development of China's modified plastics industry, innovative technology is the key point of future development.
Analysts in the chemical industry believe that the overall development level of China's modified plastics industry is not very high at present. The production scale of enterprises in the industry is generally small. There are many primary products in the product market, the quality of intermediate products is not stable enough, and the lack of advanced products is far from meeting the needs of China's current social and economic development. As an important part in the field of new chemical materials, modified plastics have been listed as one of the key scientific and technological fields for development by the state. The introduction of various domestic policies will further promote the development of the modified plastics industry. The automobile and home appliance industries are hot spots in the development of modified plastics, accounting for more than 50%.
The application of plastics in automobile industry has a history of more than 50 years. With the development of automobiles towards light weight and energy saving, higher requirements are put forward for materials. As 1kg plastic can replace 2-3 kg steel and other heavier materials, the fuel consumption can be reduced by 6% - 8% for every 10% reduction of the vehicle's dead weight. Therefore, increasing the amount of modified plastics in the vehicle can reduce the cost and weight of the vehicle, and achieve energy-saving effect. The amount of plastic used for passenger cars and commercial vehicles varies. Last year, the demand for modified PP, PC alloy and modified ABS was about 114.63, 1513 and 149700 tons respectively. The market of modified plastics for household appliances in China is mainly occupied by foreign enterprises, while domestic modified plastics enterprises occupy less than 1/3 of the market share. As the products of domestic enterprises are mostly limited to the low technology content and low standard level, they are obviously insufficient to develop the fields with high performance requirements.
According to the 2009-2012 Research Report on Market Analysis and Investment Value of China's Modified Plastics Industry, with the substantial improvement of people's living standards and the improvement of technical means, "replacing steel with plastics" and "replacing wood with plastics" will become a trend in China. The modified plastics industry, as a sub industry with the fastest development and great potential in the plastic processing industry, is expected to maintain a growth rate of more than 10% in the total market demand in China in the next five years.
