Masterbatch is a solid additive for plastic,being used for coloring plastics, and this is how color compounds are made. It is composed of pigments that disperse evenly in the resin.
The plastic masterbatch is a compound made by filling a plastic additive in a resin in an excessive amount; when manufacturing a plastic product, it is not necessary to add such a plastic additive, but it is only necessary to add the corresponding masterbatch. Therefore, it is one of the most important forms of plastic additives used in the world today. The advantages are: the process is simple, easy to use, easy to achieve automated production,improve labor productivity, but also to avoid environmental pollution, is conducive to a clean and civilized production of workers' health. The masterbatch reinforces the resin component or binder within the plastic that is dispersed by fibers or other reinforcing materials.
