Black masterbatch with dispersion effect, is also very good carrier, scattered distribution mainly role in can make pigment uniformly to the resin in the main carrier, and plays the role of transport, both of which are closely connected.
　　Dispersion of black masterbatch, mainly refers to the further dispersion and stability in pigment, resin, also must have good compatibility with resin, does not affect the coloring product quality. Polyolefin masterbatch dispersant generally use low molecular weight polyethylene wax or stearic acid zinc. Engineering plastics masterbatch dispersant generally use polar low molecular weight polyethylene wax, magnesium stearate, calcium stearate etc.. At the same time the liquidity black masterbatch carrier should be greater than be colored resin, also be after coloring does not influence the quality of products.
　　Such as using the same kind of polymer melt index is larger, the higher the melt index masterbatch by polymers, to ensure that the final product color consistency. PE, PP Color Masterbatch choose LDPE (low density polyethylene) resin as carrier, PS, select ABS masterbatch modified PS as carrier.
