Functional masterbatch refers to the concentrates of various plastic auxiliaries. Direct addition of auxiliaries is not easy to disperse, and the use efficiency is not high, so it is often added in the form of masterbatch.

Normally, we say that the functional masterbatch generally refers to: filled masterbatch, masterbatch, flame retardant masterbatch, stabilization (anti-aging) masterbatch, degradable masterbatch, anti-drip masterbatch, antistatic masterbatch, foam masterbatch , multi-functional masterbatch and so on.

The composition of the different plastic masterbatches varies, but basically consists of four layers: the inner layer is the masterbatch core; the secondary inner layer is the coupling layer, the secondary outer layer is the dispersion layer, and the outer layer is the reinforcement mixing layer.

The masterbatch reinforcements usually include carrier resins such as PP, LDPE, LLDPE, HDPE, PP, PS, HIPS, PVC, CPE, EVA, and some polar polymers such as anhydrous maleic anhydride. Ethylene, polypropylene (MAH-PE, MAH-PP).

The above is the common sense of functional masterbatch.
