A plastic colorant made of a high proportion of pigments or additives and thermoplastic resin and good dispersion, the selected resin has good wetting and dispersion effect on the colorant, and has good compatibility with the colored material. i.e. pigment + carrier + additive = masterbatch
The masterbatch technology generally used is the wet process. Masterbatch materials are made by aqueous phase grinding, phase turning, washing, drying and granulation, only in this way can product quality be guaranteed. In addition, while grinding the pigment, a series of masterbatch technical tests should be carried out, such as determining the fineness of the mortar slurry, determining the diffusion performance of the mortar slurry, determining the solid content of the mortar slurry and determining the fineness of the color paste.
Masterbatch is generally composed of three parts, colorant carrier dispersant, after mixing, crushing, extrusion and drawing into granules after mixing by high-speed mixer, masterbatch in the plastic processing process, has high concentration, good dispersion, cleanliness and other significant advantages.
