What is the technical process of color masterbatch?

A plastic colorant composed of a high proportion of pigments or additives and thermoplastic resin, which is well dispersed. The selected resin has good wetting and dispersing effects on the colorant, and has good compatibility with the colored material. Namely: pigment+carrier+additive=color masterbatch

The commonly used color masterbatch technology is a wet process. The color masterbatch is made by grinding, phase transformation, washing, drying, and granulation in water, in order to ensure the quality of the product. In addition, while grinding the pigment, a series of color master batch technology tests should also be carried out, such as measuring the fineness of the sand grinding slurry, measuring the diffusion performance of the sand grinding slurry, measuring the solid content of the sand grinding slurry, and measuring the fineness of the color slurry.

Color masterbatches are generally composed of three parts: a colorant carrier dispersant, which is mixed, crushed, and extruded into particles through a high-speed mixer. Color masterbatches have significant advantages such as high concentration, good dispersibility, and cleanliness in plastic processing.
