In terms of variety development, Chinese masterbatch manufacturers have developed masterbatch for fiber, masterbatch for film, masterbatch for wire and cable, polyolefin masterbatch, PVC masterbatch, and masterbatch for injection molding products. grain. In the future, the color masterbatch will develop in the direction of multi-function, high color content and high technology content, which is mainly reflected in the following aspects: ①Development of multi-functional masterbatch

Plastic or chemical fiber products often require products to have multiple properties at the same time. The integration of coloring and other functions into master batches is of great significance to improving the performance of plastic or chemical fiber products and simplifying their production processes. Multifunctional masterbatches include: coloring, flame-retardant and antistatic multifunctional masterbatches for coal products, coloring, antibacterial, thermal insulation, conductive masterbatches for chemical fiber fabrics, and coloring and toughening masterbatches for plastic products Grains and so on.

②Development of high-performance engineering plastics and thermoplastic elastomer masterbatch

my country's high-performance engineering plastics and thermoplastic elastomers are developing 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 all pose new challenges to the masterbatch industry. The preparation of these masterbatches is very different from traditional masterbatches in the selection of raw materials, processing technology and use conditions.

How to adapt to the ultra-high temperature processing properties of high-performance engineering plastics and the special processing rheological properties of thermoplastic elastomers will be technical difficulties.

③Development of mass masterbatch for special grades

With the rapid development of my country's plastic products industry, the output of color masterbatches will increase more than in the past. Some masterbatch varieties will no longer be directly supplied to downstream plastic products manufacturers, but directly provided to upstream petrochemical companies, using masterbatch and resin to directly make color modified materials, such as tube materials, automotive special materials, etc. The formation of this production method has transformed the color masterbatch production model, which has always been characterized by small batches and multiple varieties, into a single-variety, large-scale production model. The change in production mode will also pose challenges to the masterbatch technology. How to ensure the uniformity of the masterbatch produced 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 masterbatch.

④Development of dispersants and additives for masterbatch

With the development of multi-functional masterbatch, high-performance engineering plastics, thermoplastic elastomer masterbatch, and special grade mass masterbatch, the development of supporting dispersants and additives will also be faced by the future masterbatch industry. Important task. Such as the development of composite dispersants, high temperature resistant dispersants, processing rheological properties modifiers, etc.
