What Is The Role Of Black Masterbatch Dispersion And Carrier?
Apr 23, 2018

The black masterbatch has a dispersing effect and is a good carrier at the same time. The dispersion is mainly manifested in that the pigment can be evenly distributed into the resin, while the carrier mainly plays a transport role, and the two are closely connected.

The dispersion of black masterbatch mainly means that the pigment is further dispersed and stabilized in the resin. At the same time, it must be compatible with the resin and does not affect the quality of the coloring product. Polyolefin masterbatch dispersants generally use low molecular weight polyethylene wax or zinc stearate. The engineering plastic masterbatch dispersants generally use polar low molecular weight polyethylene wax, magnesium stearate, and calcium stearate. At the same time, the fluidity of the black masterbatch carrier should be greater than that of the pigmented resin, and at the same time it will not affect the product quality after being colored.

For example, if a polymer with the same melt index is used, the melt index of the masterbatch is higher than that of the polymer, so as to ensure the consistency of the final product. PE, PP color masterbatch LDPE (low density polyethylene) resin as the carrier, PS, ABS masterbatch selected modified PS as carrier.
