What Is The Technical Process Of Masterbatch?
- Sep 20, 2018 -

A plastic colorant which is well dispersed by a high proportion of pigments or additives and thermoplastic resins, the resin selected for which has good wetting and dispersing effect on the colorant and has good compatibility with the material to be colored.

The commonly used masterbatch technology is a wet process. The masterbatch is made by aqueous phase grinding, phase inversion, water washing, drying and granulation. Only the quality of the product can be guaranteed. In addition, while the pigment is being processed, a series of masterbatch techniques should be tested, such as determining the fineness of the sanding slurry, measuring the diffusion properties of the sanding slurry, determining the solid content of the sanding slurry, and measuring the fineness of the colorant. project.

The masterbatch is generally composed of three parts. The colorant carrier dispersant is kneaded by a high-speed mixer, crushed, and extruded into pellets. The masterbatch has high concentration, good dispersibility and cleanness during plastic processing. And so on.
