The future development direction of China's modified engineering plastics industry

Looking at the overall picture of China's plastics industry and comparing it with developed industrial countries, it is not difficult to find that there is a lack of a transitional industry between large petrochemical enterprises providing large quantities of general-purpose synthetic resins and plastic products processing enterprises directly used by production consumers. The company mainly produces small-volume, multi-variety products that are adaptable to a wide range of high-performance products. It provides a wide range of intermediate or special materials for downstream plastics processing enterprises. At present, the functions of this industry are often dispersed in large and medium-sized plastic products processing plants, and intermediate products or special materials are provided by a certain workshop or process. The actual situation shows that on the one hand, small enterprises are not conducive to the improvement of product quality, and economically not economical. On the other hand, some intermediate products are impossible to establish themselves in downstream enterprises. For example, color masterbatch, which is necessary for coloring various plastic products and materials, special color masterbatch production plants are specialized to provide products suitable for a variety of resins and colors, which is the most suitable. It is obviously uneconomical and unreasonable for companies that color plastic products to produce masterbatches.

After years of practice and understanding, the modified plastic products have been professionalized in several aspects and have shown great vitality. For example, the filling masterbatch with heavy calcium carbonate as filler for many polyolefin plastic products has more than ten domestic production capacity of more than 3,000 tons. The total production capacity of hundreds of filled masterbatch products in the country has exceeded. 200,000 tons. In recent years, companies that mainly produce modified materials for automobiles and home appliances have gradually emerged. The output value and profit of special materials not only grow at a high speed, but also become the dominant products of some plastic processing plants. We have reason to believe that the modified plastics industry achieves specialized production and becomes a leading product of various modified plastic materials such as reinforcement, blending and filling between the resin raw material production plant of the petrochemical enterprise and the plastics processing plant of the end user. An industrial team has a bright future. With the continuous strengthening of China's economic strength and the rapid transformation of scientific research results, China's modified plastics industry will surely take a new stage of development.
