According to Dezhou Kecai New Materials Co., Ltd., plastic coloring is an indispensable part of plastic processing, and the choice of coloring agent is directly related to the final effect of plastic products. Today, let's talk about plastic colorants, especially the three common colorants, toner, masterbatch and color paste, to see their respective advantages and disadvantages, so that everyone can better choose and use them in injection molding production or other processing methods of plastics.
First of all, talk about toner coloring. Toner is to directly add pigments or dyes to plastic particles in powder form. This method is simple and direct, and the cost is relatively low. Its advantage is good dispersibility, and it is especially suitable for small batch plastic processing. But the disadvantages are also obvious, that is, it is easy to produce flying dust pollution, which affects the working environment, and cleaning the hopper when changing colors is also a headache. In addition, for products such as film blowing and spinning, color powder coloring may not be so reliable, because pigment powder may not be fully combined with resin, resulting in "sandwich"
Phenomenon.

The next step is masterbatch coloring. Color masterbatch, simply put, is to mix pigment into carrier resin and make it into particles about the size of resin particles. In this way, the problem of toner flying is solved, and color change is much more convenient. Moreover, the color masterbatch coloring has strong pertinence, simple color matching and easy quantification. However, the dispersion of color masterbatch may be almost, and the cost is higher. Also, if there is a difference between the carrier in the masterbatch and the resin to be colored, there may be some problems on the surface of plastic products, such as undivided spots, spots and patterns.

Let's talk about color paste coloring. Color paste is a semi-finished product made by dispersing pigments and fillers in paint. The advantages of color paste are easy to use, good high temperature resistance and convenient storage, and it can also reduce the problem of dust pollution in the use of toner. Moreover, it is easy to control the input of color paste in use, reduce color difference, and improve coloring power and color brightness. However, high-quality color paste requires higher technology and raw material quality, and the cost may be higher than that of masterbatch and toner. Also, if the addition amount is large, the screw may slip; After storage for a long time, precipitation may occur.
When selecting plastic colorants, we need to comprehensively consider the use requirements, processing conditions, cost and environmental protection of the products. Only by fully understanding the advantages and disadvantages of various colorants can we make the most suitable choice and make the products show the best effect.
