Colorants cannot react with resins and various auxiliaries, have strong solvent resistance, low migration, and good heat resistance. That is, masterbatches cannot participate in various chemical reactions. For example, carbon black can control the curing reaction of polyester plastics, so carbon black cannot be added to polyester. The dispersibility and tinting power of the colorant should be good. When the colorant is not uniformly dispersed, it will affect the appearance performance of the product; when the coloring power of the colorant is poor, the amount of colorant will increase, and the material cost will increase. The dispersibility and tinting power of the same colorant in different resins are not the same, so you should pay attention to this when selecting a colorant.

Black masterbatch for granulation, the main products are:

A) Professional black mother and plastic color matching.

B) Professional analysis: professional technicians provide customers with material analysis; solve technical problems, color difference analysis.

Precautions for masterbatch use:

1. The color masterbatch will absorb moisture after storage for a period of time, especially PET, ABS, PA, PC, etc., so it should be dried according to the same process as the color masterbatch to meet the moisture content requirement.

2. The color masterbatch must be used to achieve the desired color and luster, and color differences and color light changes often occur.

3. Masterbatch and other additives will react, pay attention when using.

4. Attention should be paid to the selection of the dilution ratio of the masterbatch. Use high dilution ratio, the production cost is low, but it is also limited by processing equipment; special black masterbatch for pumping

You should understand the other properties of colorants. For example, for plastic products used in food and children's toys, colorants should be non-toxic. For plastic products used in electrical appliances, colorants with good electrical insulation should be selected. For outdoor use In terms of plastic products, colorants with good weather resistance should be selected.
