Nowadays, there are many color masterbatch manufacturers in our lives. Although the demand for color masterbatch is very large in the market, the competition among these manufacturers is also very large. There are also some inferior materials produced in the market. So we need to pay attention to its quality problems when choosing the color masterbatch. When selecting the color masterbatch, the user should pay attention to the following points:

1. Before selecting the color masterbatch, we should first understand the other properties of the colorant. For plastic products used in food and children's toys, the coloring materials should be non-toxic; for plastic products used in electrical appliances, coloring materials with good electrical insulation should be selected; for outdoor plastic products, weathering resistance material with good aging properties should be selected.

2. Secondly, we also need to ensure that the selected colorants do not react with the resin and various additives, and should also have the advantages of strong solvent resistance, low mobility, and good heat resistance. That is to say, the color masterbatch cannot participate in various chemical reactions. If carbon black can control the curing reaction of polyester plastic, carbon black can not be added to the polyester.

3. The dispersibility and coloring power of the colorant should be good. When the color material is unevenly dispersed, it will affect the appearance performance of the product; when the coloring power of the color material is poor, the amount of color material will increase and the material cost will increase. The dispersibility and tinting strength of the same colorant in different resins are not the same, so pay attention to this when selecting the colorant; the particle size of the colorant is also related to the dispersibility. The smaller the particle size, the better the dispersion. The tinting strength is also strong.
