Knowledge of color masterbatch details

1、 What is color master?

Color masterbatch is a new kind of special colorant for polymer materials. To put it simply, color masterbatch is an aggregate made by uniformly loading pigments or dyes into resins. 2、 What are the basic ingredients of color masterbatch? The basic components of color masterbatch are: 1. Pigments or dyes, which are divided into organic pigments and inorganic pigments.

2、 The carrier is the matrix of color masterbatch.

The special color masterbatch generally selects the same resin as the product resin as the carrier, which has good compatibility, but also needs to consider the mobility of the carrier. Dispersant: It can make the pigment disperse uniformly and no longer agglomerate. The melting point of the dispersant should be lower than that of the resin, and it has good compatibility with the resin and good affinity with the pigment. Common dispersants are polyethylene low molecular wax and stearate. Additives: such as flame retardant, brightening, anti-static, anti-oxidation and other varieties. Generally, the color masterbatch does not contain the above additives unless required by customers.

3、 What are the varieties and grades of color masterbatch?

The common classification methods of color masterbatch are as follows: classification by carrier: PE color masterbatch, PP color masterbatch, ABS color masterbatch, PVC color masterbatch, EVA color masterbatch, etc. are classified by use: the heat resistance grade of special color masterbatch such as injection color masterbatch, blow molding color masterbatch, spinning color masterbatch, etc. is generally compatible with the plastic used for products, and can be used safely under normal temperature. Only under the following circumstances can discoloration be caused to varying degrees: first, the temperature is not within the normal range; second, the shutdown time is too long. Compared with pelleting coloring, color masterbatch coloring has the following advantages: coloring and product processing are completed at one time, avoiding the heating process of pelleting coloring on plastics, and protecting the quality of plastic products.
