New chemical materials are an important branch of new materials industry and the most dynamic and potential field in basic chemical industry. The development of new chemical materials industry is promising in breaking through the bottleneck of domestic resources, protecting the environment, adjusting the industrial structure, and maintaining the stable, rapid and sustainable development of the petroleum and chemical industries. 20 1 1 China's dependence on foreign crude oil has exceeded 55%, exceeding the warning line of 50% for three consecutive years. It is estimated that the dependence on foreign countries will reach 67% by 2020. The energy utilization rate of domestic petrochemical industry is lower than that of developed countries 15%, while the unit energy consumption of some products is 20%-30% higher. The structural contradiction of domestic petrochemical products is prominent, and more than 65% of the total output value is composed of oil and gas exploitation, refined oil, basic chemical raw materials, fertilizers and other primary processing products, which cannot meet the needs of related industries.

Policy "Spring Breeze" promotes development. New chemical materials are one of the emerging industries in the field of low-carbon economy supported by the state. According to "Decision on Accelerating the Cultivation and Development of Strategic Emerging Industries" and "Twelfth Five-Year Development Plan for New Materials Industry", chemical new materials industry has become the leading industry in the national economy. The Outline of the Twelfth Five-Year Plan for the Development of Science and Technology in Petroleum and Chemical Industry proposes that by 20 15, the gap between the overall technical level of domestic high-end chemical new materials and developed countries will be reduced to about 10, reaching the international advanced level at the beginning of this century. The Twelfth Five-Year Development Plan for Petrochemical Industry puts forward that the development priorities of new chemical materials in the Twelfth Five-Year Plan include: special synthetic rubber, engineering plastics, high-performance fibers, fluorosilicone materials, degradable materials, functional membrane materials, functional polymer materials and composite materials.

There is a huge market gap in the domestic chemical new materials market, and the import volume accounts for most of the domestic market share. The overall self-sufficiency rate of new chemical materials in China is about 56%, of which the self-sufficiency rate of new chemical materials in new fields is only 52%, and the self-sufficiency rates of engineering plastics and special rubber are only 35% and 30%. Generally speaking, chemical new material products will go through the process of product gross margin fluctuation and import substitution rate rising. In the process of import substitution of new chemical materials, the contradiction of oversupply of most products is not prominent, and some products are in short supply. Enterprises with core technologies can gain profits proportional to investment by expanding production capacity, and most enterprises can achieve sustained and rapid growth. High barriers bring high returns, and the gross profit margin of advanced chemical new materials products is above 70%, far exceeding the industry average profit of bulk chemicals of about 15%.
