Three develpoment directions of masterbatch industry technology

2020-03-24 17:26:50

In terms of variety development, China's masterbatch manufacturers have developed masterbatches for fibers, masterbatches for films, masterbatches for wires and cables, polyolefin masterbatches, PVC masterbatches, and masterbatches for injection molded products. grain. In the future, color masterbatches will develop in the direction of multifunctionality, high color content and high technology content.

    1. Development of multifunctional masterbatch

The application of high-performance, differentiated, and ecological fibers is continuously expanding to industrial fields such as transportation, new energy, medical and health, infrastructure, safety protection, environmental protection, and aerospace. With the in-depth adjustment of China's economic structure, the acceleration of urbanization, and the continuous expansion of individualized, differentiated, and functional consumer demand, the pace of China's chemical fiber industry's supply-side structural reform will accelerate, improving the quality of the industry as a whole. Efficiency and the development of high-quality capacity provide new opportunities.

It is estimated that in the next 5 years, the annual output of functional fibers will reach 4.6 million to 5 million tons, of which the proportion of functional masterbatches is expected to reach 20%.

    2.Development of high-performance engineering plastics and thermoplastic elastomer masterbatches

China's high-performance engineering plastics and thermoplastic elastomers have developed rapidly, such as thermoplastic fluoroplastics and thermoplastic polyurethanes, and their products also need to be colored with masterbatches. For example, polyperfluoroethylene propylene masterbatch, polyvinylidene fluoride masterbatch, and thermoplastic polyurethane masterbatch have all brought new challenges to the masterbatch industry. The preparation of these color masterbatches is very different from traditional color masterbatches in the choice of raw materials, processing technology and use conditions. How to adapt to the ultra-high-temperature processing performance of high-performance engineering plastics and the special processing rheological characteristics of thermoplastic elastomers will be technical difficulties.

 

 

    3.Development of large-scale master batches of special grades

With the rapid development of China's plastic products industry, the output of masterbatches will increase greatly compared to the past. Some masterbatch varieties will no longer be directly supplied to downstream plastic product manufacturers, but will be directly provided to upstream petrochemical companies. Color masterbatches and resins will be directly used to make color modified materials, such as pipe materials and automotive materials. The formation of this production mode has transformed the production mode of masterbatch, which has always been characterized by small batches and multiple varieties, 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 uniformity of the produced 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.
