China's modified plastics industry has a large room for development. The data shows that the total output of plastics in China has increased from nearly 18 million tons in 2004 to nearly 80 million tons in 2016, and the modification rate has also increased from 8% to 19%. However, compared to 40% of the world's modified plastics used in the automotive industry, China is only about 10%. An important indicator to measure the development level of a country's plastics industry - plastic-steel ratio, China is only 30:70, less than the world average of 50:50, far less than developed countries such as the United States 70:30 and Germany's 63:37. There is still a big gap between China's per capita plastic consumption and the developed countries in the world.
Future development trend of modified plastics
There are mainly the following aspects:
During the "Thirteenth Five-Year Plan" period, China's synthetic resin industry will focus on the requirements of lightweight, high strength, high temperature resistance, shock absorption and sealing in the fields of automobiles, modern rail transit, aerospace and other fields, and intensify the development of innovation and strive to improve The quality of engineering plastic products accelerates the development of high-end products such as long carbon chain nylon, high temperature resistant nylon, amorphous copolyester (PETG), thermoplastic polyester elastomer (TPEE), and high performance polyoxymethylene modified products.
Accelerate the development of key supporting monomers and engineering plastic alloys, focusing on the development of modified plastic products with enhanced, toughened, heat-resistant, spray-free, microcellular foaming, and low volatile organic compounds (VOC). Strive to achieve more than 70% domestic self-sufficiency rate of engineering plastics by 2020, and the self-sufficiency rate of high-end polyolefins is close to 70%, and the special polyester engineering plastics with better foundation will achieve net export.
General plastics engineering: Although the number of new engineering plastics continues to increase, the application fields are constantly expanding, and the cost is gradually reduced due to the expansion of production equipment.
High-performance engineering plastics: With the vigorous development of the domestic automotive, electronic and electrical, communications and machinery industries, the demand for modified plastic engineering plastics will increase significantly, and various high-strength and heat-resistant engineering plastics will be widely used.
The development of new high-efficiency additives has become another important direction for the development of modified plastics: additives for modified plastics, in addition to additives commonly used in plastic processing, such as heat stabilizers, antioxidants, UV absorbers, nucleating agents, antistatic agents. In addition to dispersants, flame retardants, etc., toughening agents, flame retardant synergists, alloy compatibilizers (interfacial compatibilizers) have a very critical impact on the performance of modified plastics.
With the rapid development of China's plastic products industry, the production of masterbatch will increase significantly compared with the past. Some masterbatch varieties will no longer be directly supplied to downstream plastics manufacturers, but will be directly supplied to upstream petrochemical enterprises. Color masterbatch and resin will be directly used to make color modified materials, such as pipe materials and automotive special materials.
Modified plastics opportunity
On December 19, the State Council issued the "13th Five-Year Plan for the Development of Strategic Emerging Industries". During the "13th Five-Year Plan" period, China will use the research and development of modified plastics as a breakthrough to focus on improving the technological innovation capability and comprehensively improving the plastics industry. techinque level.
In the development plan of "Made in China 2025" issued by the Chinese government, new materials are listed as one of the key development areas, and synthetic resin is an important part of the new materials industry. The synthetic resin industry will become a period in the future. Key industries for development.
Lightweight vehicles provide new opportunities for the development of the modified plastics industry. Lightweight has become the focus of today's new car development. To achieve the goal of lightweighting, in addition to optimizing the structure and process design, most of them focus on the selection of materials. Currently, automotive modified plastics are widely used in parts such as bumpers, engine covers, airbags and seat belts.
The integration of high-performance plastic not only reduces the weight of the car, but also plays the role of shock absorption and wear resistance, thus further extending the service life of the car. Compared with 42% of the world's modified plastics used in the automotive industry, it is only about 10% in China. It is expected that the automotive industry will become the fastest growing area of ​​engineering plastics consumption in the next few years. By 2020, the annual output of China's automobiles will reach 28.46 million. According to the conservative use of 300kg/set of automotive modified plastics, the compound annual growth rate of the automotive modified plastics industry will reach 25.89% in the next five years.
Application of modified plastics
Modified plastics are widely used, mainly in the automotive industry, home appliance industry, electrical and electronic industry, construction industry, medical industry and many other industries. With the trend of “plasticizing steel†and “lightweight automobile, light and fashionable home appliances†Impact, the gradual implementation of policies such as “new urbanization†and “building beautiful Chinaâ€, the application products of the industry will be further expanded, and the technological upgrading and innovation of enterprises and the optimization and adjustment of product structure will bring broad development prospects for the industry. .
China's plastic consumption has grown steadily and has entered the ranks of the world's major powers. In 2014, the global demand for modified plastics was 130 million tons. In 2015 this value increased to 144 million tons. During the period 2014-2020, the global compound plastics demand will grow at a compound annual growth rate of 4.6%. The main development goals of the industry in the “13th Five-Year Plan†are: the annual output of modified plastic products will increase by about 15%, the total industrial output value will increase by about 12% annually, and the total profit, total profits and taxes will increase by about 16% annually. The growth rate is about 10%, and the output rate of new products and the contribution rate of scientific and technological progress are increased to 10% and 40% respectively, and the development potential is huge.
The main types of modified plastic products are flame retardant resins, reinforced and toughened resins, plastic alloys, functional color masters and so on. At present, there is still a gap between China's modified plastics production enterprises and foreign countries. During the "13th Five-Year Plan" period, it 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 can Go up one more step.
