Masterbatch coloring - Produce high-concentration colored granular masterbatches, then mix the masterbatches evenly with the natural-color plastic particles that need to be colored, and directly make plastic parts.
1. Good dispersibility
Color masterbatch is a complex produced through special processing of colorants and specific additives. During the process of preparing color masterbatches, the colorant has been well pre-dispersed, which can avoid the existence of coarse particles of the colorant and thus eliminate the appearance of color spots in colored plastic products. At the same time, it is easy to stir the color masterbatch and plastic particles evenly. When coloring with color masterbatch, the uniformity of the color of plastic products is also relatively good.
2. Convenient to use
Due to the good mixing performance between color masterbatch and plastic particles, common ordinary mixing equipment can be used, or even manual mixing methods can be employed to achieve uniform mixing, which is very convenient to apply.
3. It helps to reduce the color difference of plastic products
In masterbatches, apart from colorants, there are also carriers and other additives. Therefore, the amount of masterbatch added to a unit of plastic is higher than that of ordinary colorants. As a result, the relative measurement error is smaller, which helps to reduce color differences during coloring.
4. The working conditions are relatively good
Color masterbatch coloring is adopted. The colorant has been combined with the carrier and other additives and made into granular form. During measurement and mixing processing, it will not fly, thus not polluting the environment. Compared with dry coloring, it greatly improves the working conditions.
5. It is very convenient to change colors
Coloring with color masterbatches will not contaminate the mixing equipment. When changing colors, the work of cleaning the mixing equipment can be saved. Compared with dry coloring and paste coloring agent coloring, it has the advantages of saving time and labor.
