Plastic masterbatch belongs to the middle of the plastic products industry. It is the downstream of pigments and petrochemical products and the upstream of plastic products. It plays an important role and position in the plastic products industry.

The important position and role of plastic masterbatch in the plastics industry are manifested in four aspects:

(1) The advantages of coloring properties of plastic masterbatch are outstanding
Since the coloring agent directly contacts the air during storage and use, moisture absorption, oxidation, agglomeration, and the like are apt to occur. When used directly, color spots appear on the surface of the plastic product, the hue is dark, and the color is easily faded. The masterbatch is mechanically processed in the production process, and the coloring agent is refined, and the coloring agent, the resin carrier and various additives are thoroughly mixed to separate the coloring agent from air and moisture, thereby enhancing the coloring agent. The weather resistance, the dispersibility of the colorant and the coloring power are improved.

(2) Plastic masterbatch is the key factor determining the quality of downstream plastic products
The proportion of color masterbatch added to plastic products is generally more than 2%. Although the cost in the production of downstream enterprises is relatively low, it has an important influence on the aesthetics and quality of plastic products. Plastic products are generally produced in a large scale and continuous manner. If the technical indicators such as color difference, dispersibility and migration resistance of the masterbatch used are not up to standard, the quality of the whole batch of products will be lowered or even scrapped. Therefore, downstream customers pay great attention to it. The quality of the masterbatch is equal in quality and quality stability. The development and deepening of masterbatch technology has promoted technological advancement and industrial growth in the plastics industry.

(3) Plastic masterbatch can promote the clean production of downstream plastic products industry
The use of masterbatch in the production of plastic products can reduce the emission of dust, sewage and other pollutants as a whole, protect the health of employees, and reduce the waste of colorants, in line with the industrial policy orientation and green industry trends. Downstream plastics manufacturers are prone to dust and dust when adding and mixing traditional powdered coloring materials, which may cause health damage to production personnel, and often require cleaning of the working environment, resulting in a large discharge of pigment wastewater. In addition, the dispersion of the conventional powdery coloring material in the resin is inferior to that of the masterbatch, resulting in a greater amount of addition under the same coloring requirements. Liquid coloring materials tend to spill when added and mixed, and may flow out during cleaning, which may cause water pollution.

The color masterbatch disperses the colorant in the carrier resin, and the dust is less during the addition and mixing process; the downstream product company colored with the masterbatch is clean, the cleaning is simple, the wastewater discharge is reduced, and the downstream plastic product manufacturing enterprise is cleaned. Trends and requirements. The color masterbatch has good dispersibility and reduces the waste of colorant.

(4) Reduce downstream comprehensive use costs
Since the masterbatch is similar in shape to the resin particles, it is more convenient and accurate in metering, and does not adhere to the container during mixing, thereby saving time for cleaning the container and the machine and raw materials used for cleaning. Adding a small amount of functional masterbatch to a large amount of resin for processing a single time becomes a product. Compared with the modified plastic technology from resin to product to undergo two processing processes, most of the materials experience a single processing process, which not only saves processing costs, but also is more favorable to maintain product performance. Functional masterbatch presents a single alternative trend for modified plastics.
