The use of plastic products plays a very important role in people's daily life. All kinds of plastic products can appear in almost every article. It is precisely because of this that the development of the plastic industry has always been very prosperous.

　　In the plastic industry, plastic masterbatch is an important content that can not be ignored. It is a special concentrated raw material for synthesis. As long as plastic masterbatch is used, there is no need to add other plastic additives and save a lot of materials. Then, what is the structure of plastic masterbatch?

　　The structure of plastic masterbatch is mainly composed of four parts:

　　1. The first layer is the filler core, which mainly improves the rigidity and reduces the cost. Selection of filler core: calcium carbonate, talc powder, kaolin, wollastonite, fly ash, glass beads and so on can be used as filler core.

　　2. The second layer is a coupling layer, which is composed of coupling agent or cross-linking agent to improve the binding force between filler and resin.

　　3. The third layer is a dispersion layer, which is composed of some oligomers and dispersants. The purpose is to mix evenly, avoid filler aggregation and improve fluidity in the granulation process.

　　4. The fourth layer is the mixing layer, which is composed of copolymer or compatibilizer with certain double bond, so as to better combine with the resin to be filled.
