The role of plastic masterbatch is manifested in four aspects:

(1) The coloring performance advantage of plastic masterbatch  is outstanding

Since the colorant directly contacts the air during storage and use, it is prone to moisture absorption, oxidation, agglomeration and other phenomena. Direct use will cause color spots on the surface of plastic products, the color will be dark, and the color will easily fade. The color masterbatch is mechanically processed in the production process, the colorant is refined, and the colorant, resin carrier and various additives are fully mixed to isolate the colorant from air and moisture, thereby enhancing the colorant. excellent weather resistance, improved dispersibility and tinting strength of colorants.

(2) Plastic masterbatch  is one of the key factors determining the quality of downstream plastic products

The addition ratio of color masterbatch in plastic products is generally more than 2%. Although the cost in the production link of downstream enterprises is relatively low, it has an important impact on the appearance and quality of plastic products. Plastic products are generally produced on a large scale and continuously. If the technical indicators such as color difference, dispersion and migration resistance of the color masterbatch used do not meet the standards, the quality of the whole batch of products will often decline or even be scrapped. Therefore, downstream customers pay great attention to The quality of the masterbatch is high and the quality is stable. The development and deepening of color masterbatch technology has promoted the technological progress and industrial upgrading of the plastic products industry.

(3) Plastic masterbatch  can promote cleaner production in the downstream plastic products industry

The use of color masterbatch in the production of plastic products can reduce the discharge of pollutants such as dust and sewage on the whole, protect the health of employees, and reduce the waste of colorants, which is in line with the industrial policy orientation of various regions and the industry trend of green environmental protection. When adding and mixing traditional powdery coloring materials, downstream plastic manufacturers are prone to cause dust flying, which may cause health damage to production personnel, and the working environment needs to be cleaned frequently, resulting in a large amount of pigment waste water. In addition, the dispersibility of traditional powdery coloring materials in resins is worse than that of color masterbatches, resulting in more additions under the same coloring requirements. The liquid coloring material is easy to be spilled when adding and mixing, and may flow out during cleaning, which is likely to cause water pollution.

The color masterbatch disperses the colorant in the carrier resin, and there is less dust in the process of adding and mixing; the production environment of downstream product enterprises that use color masterbatch for coloring is clean, easy to clean, and reduces waste water discharge, which is suitable for the clean production of downstream plastic product manufacturers trends and requirements. The color masterbatch has good dispersibility and reduces the waste of colorant.

(4) Reduce the cost of comprehensive downstream use

Since the color masterbatch is similar in shape to the resin particle, it is more convenient and accurate in metering, and it will not stick to the container during mixing, thus saving the time for cleaning the container and the machine, as well as the raw materials used for cleaning the machine. A small amount of functional masterbatch is added to a large amount of resin to be processed in a single time to become a product. Compared with the modified plastic technology, which has to go through two processing processes from resin to product, most of the materials go through a single processing process less, which not only saves processing costs, but also more conducive to maintaining product performance. Functional masterbatches have a tendency to substitute for modified plastics.
