The functional masterbatch refers to a concentrate of various plastic auxiliaries. The direct addition additive is not easy to disperse, and the use efficiency is not high, so it is often added in the form of a masterbatch.

Generally speaking, the functional masterbatch generally refers to: filler masterbatch, color masterbatch, flame retardant masterbatch, stabilized (anti-aging) masterbatch, degradation masterbatch, anti-drip masterbatch, antistatic masterbatch, foaming masterbatch , multi-functional masterbatch, etc.

Different plastic masterbatch compositions are different, but basically consist of four layers: the inner layer is the masterbatch core; the second inner layer is the coupling layer, the second outer layer is the dispersion layer, and the outer layer is the additive layer.

The masterbatch of the masterbatch is usually selected from the group consisting of PP, LDPE, LLDPE, HDPE, PP, PS, HIPS, PVC, CPE, EVA, and some polar polymers such as anhydrous maleic anhydride grafted. Ethylene, polypropylene (MAH-PE, MAH-PP).
