Color masterbatch has the following advantages: 1 To improve the dispersibility of pigments in products, it is necessary to refine the pigments during the production process of color masterbatch to improve their dispersibility and coloring power. The carrier of the specialized color masterbatch is the same as the plastic variety of the product, with good compatibility, and can be heated and melted. The pigment particles can be well dispersed in the plastic products. When using color masterbatch, attention should be paid to the matching relationship between color masterbatch, plastic raw materials, and additives. The selection points are as follows in three aspects.

(1) Color masterbatch cannot react with resins and various additives, has strong solvent resistance, low migration, and good heat resistance. That is to say, the color masterbatch cannot participate in various chemical reactions. Carbon black can control the curing reaction of polyester plastics, so carbon black masterbatch cannot be added to polyester.

PLASBLAK? PE6021 contains high concentration carbon black, which not only provides outstanding coloring strength and covering ability, but also maintains the basic mechanical properties of plastics. By combining different qualities of recycled resin, the amount of masterbatch used can be reduced by 10-15% compared to current products, achieving the same coloring effect. When maintaining the basic mechanical properties of plastics, such as tensile strength, and due to the high processing temperature of plastic products, the color masterbatch should not decompose or change color under the heating temperature conditions. Generally, inorganic pigments have good heat resistance, while organic pigments and dyes have poor heat resistance. This should be given sufficient attention when selecting color masterbatch varieties.

(2) The dispersibility and coloring power of the color masterbatch should be good. Uneven dispersion of color masterbatch can affect the appearance performance of the product; When the coloring power of color masterbatch is poor, it will increase the amount of color masterbatch and increase the material cost. The dispersibility and coloring power of the same color masterbatch are not the same in different resins, so attention should be paid to this when selecting color masterbatches.

The particle size of color masterbatch is also related to its dispersibility. The smaller the particle size of color masterbatch, the better its dispersibility and coloring power.

(3) It is necessary to understand the other properties of color masterbatch, such as the requirement that color masterbatch should be non-toxic for plastic products used in food and children's toys; For plastic products used in electrical appliances, color masterbatches with good electrical insulation should be selected; For outdoor plastic products, color masterbatch with good weather aging resistance should be selected.
