Masterbatch is a polymer composite coloring material, which is composed of three basic elements: pigment or dye, carrier and additive. Specifically:

1. Composition and manufacturing : It uses resin as a carrier, adds a high proportion of pigments, dispersants and functional additives, and is made through high-speed mixing, melt-mixing extrusion, cooling and pelletizing.

2. Advantages : Masterbatch has the advantages of good coloring effect, energy saving, environmental protection, easy storage and transportation, etc. Its coloring ability is higher than the pigment itself because the concentration of pigment in masterbatch is higher.

3. Application : Masterbatch is widely used in the coloring of plastic products, including chemical fiber products and other plastic products. Its use can reduce the color matching and pigment addition of downstream plastic product companies, and improve production efficiency and product quality.

4. Classification : Masterbatches can be classified into PE masterbatches, PP masterbatches, ABS masterbatches, PVC masterbatches, EVA masterbatches, etc. according to different carriers; they can be classified into injection masterbatches, injection molding masterbatches, spinning masterbatches, etc. according to their uses. In addition, masterbatches also have different grades, such as high-grade and general grades, which are suitable for coloring high-quality and general-quality plastic products respectively.

5. Market status : The masterbatch industry is showing a good development momentum worldwide. Taking China as an example, according to statistics, the output of masterbatches is increasing year by year, and there are thousands of masterbatch manufacturers in the market. However, the overall scale of domestic masterbatch enterprises is not large, and there is no leading enterprise that occupies an absolute dominant position.

In summary, masterbatch, as an efficient and environmentally friendly coloring material, plays an important role in the plastics industry. With the development of the plastics industry, the application areas and market demand of masterbatch are also expanding.
