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.

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.
