Modified plastics are widely used, mainly in the automobile industry, home appliance industry, electronic and electrical industry, construction industry, medical industry and many other industries. With the influence of the trends of "replacing steel with plastic" and "automobile lightweight, home appliances lightweight and fashionable", the gradual implementation of policies such as "new urbanization" and "building a beautiful China", the application products of this industry will be further expanded, The technological upgrading and innovation of enterprises and the optimization and adjustment of product structure have brought broad development prospects for the industry.
Modified plastic refers to adding suitable modifiers into the matrix of general-purpose plastics and engineering plastics, and processing and modifying them through filling, blending, reinforcement and other methods to improve the flame retardancy, impact resistance, strength, tensile property and toughness of plastics.
Development overview over the years
China's plastic consumption has grown steadily and has entered the ranks of world powers. The main development goals of the industry in the "13th five year plan" in the future are: the output of modified plastic products will increase by about 15% annually, the total industrial output value will increase by about 12%, the total profits and profits and taxes will increase by about 16%, the import and export trade volume will increase by about 10%, and the output value rate of new products and the contribution rate of scientific and technological progress will increase to 10% and 40%, respectively, with great development potential.
Analysis of future development trend
China's modified plastics industry has great development space. Data show that compared with 40% of modified plastics used in the automobile industry in the world, only about 10% are used in China. The ratio of plastic to steel, an important indicator to measure the development level of a country's plastic industry, is only 30:70 in China, which is less than the world average of 50:50, and further less than the 70:30 of developed countries such as the United States and 63:37 of Germany. There is still a big gap between China's per capita plastic consumption and that of developed countries in the world.
The future development trend mainly includes the following aspects:
1. During the "13th five year plan" period, China's synthetic resin industry will focus on the requirements of light weight, high strength, high temperature resistance, shock absorption, sealing and other aspects in the fields of automobiles, modern rail transit, aerospace and so on, intensify innovation and development, strive to improve the quality of engineering plastics products, and accelerate the development of long carbon chain nylon, high temperature resistant nylon, amorphous copolyester (PETG), thermoplastic polyester elastomer (TPEE) High performance POM modified products and other high-end products.
2. Accelerate the development of key supporting monomers and engineering plastic alloys, and focus on the development of modified plastic products with reinforcement, toughening, heat resistance, spray free, microcellular foaming and low volatile organic compounds (VOCs). By 2020, the domestic self-sufficiency rate of engineering plastics will reach more than 70%, and the self-sufficiency rate of high-end polyolefins will approach 70%. Among them, the special polyester engineering plastics with better foundation will achieve net export.
3. Engineering of General Plastics: Although the number of new products of engineering plastics is increasing, the application field is expanding, and the cost is gradually reduced due to the expansion of production equipment. However, with the continuous development and maturity of modification equipment and technology, general thermoplastic resins gradually have engineering characteristics through modification, and have occupied part of the application market of traditional engineering plastics.
4. High performance engineering plastics: with the vigorous development of domestic automobile, electronic and electrical, communication and machinery industries, the demand for modified plastics and engineering plastics will increase significantly, and various high-strength and heat-resistant engineering plastics will be widely used.
5. The development of new high-efficiency additives has become another important direction of the development of modified plastics: in addition to the additives commonly used in plastic processing, such as heat stabilizers, antioxidants, ultraviolet absorbers, nucleators, antistatic agents, dispersants and flame retardants, tougheners, flame retardants and synergists, alloy compatibilizers (interfacial compatibilizers) also have a very critical impact on the performance improvement of modified plastics.
6. With the rapid development of China's plastic products industry, the output of Color Masterbatch will increase greatly compared with the past. Some color masterbatch varieties will no longer be directly supplied to downstream plastic product manufacturers, but will be directly supplied to upstream petrochemical enterprises, and color modified materials, such as pipe materials and automobile special materials, will be directly made from color masterbatch and resin. The formation of this production mode has made the color masterbatch production mode, which used to be characterized by small batch and multiple varieties, partially transform into a single variety and large-scale production mode. The change of production mode will also challenge the color masterbatch technology. How to ensure the homogeneity of the color masterbatch for a long time and how to adapt to the large-scale screw granulation technology will be the technical problems to be solved by this color masterbatch.
7. The development space of modified plastics is huge, and environmental friendly products are favored. With the continuous strengthening of environmental protection in 2018, high-performance environmental protection modified engineering plastics will usher in great development in the future.

summary
The 13th Five Year Plan period is a critical moment for the development of China's modified plastics industry. It is estimated that the main development goals of the industry in the "13th five year plan" in the future: the output of modified plastic products will increase by about 15% annually, the total industrial output value will increase by about 12%, the total profits and profits and taxes will increase by about 16%, the import and export trade volume will increase by about 10%, and the output value rate of new products and the contribution rate of scientific and technological progress will increase to 10% and 40% respectively.
At present, there is still a gap between China's modified plastics production enterprises and foreign countries. The "13th five year plan" period is an excellent period for enterprises to achieve profit growth. I believe that when the "13th five year plan" is completed, China's modified plastics industry will be able to go to a higher level and there will be more excellent enterprises that can compete with large international enterprises.
