The importance of flowability of color masterbatch
The activity of plastic melt plays a crucial role in the processing of plastic products. Especially when using color masterbatch for coloring, the activity rate of the color masterbatch should be consistent with the rate of the resin, so that it can be more uniform during blending and produce products with higher qualification rates.
The activity of white masterbatch can be expressed as Melt Index (MI), with low activity difference and high activity good. Good activity means good processing performance, low machine torque, and low power consumption.
When choosing a white masterbatch, users should not only require the masterbatch to have good activity, but also pay attention to the compatibility of the masterbatch with the carrier resin in their own factory products. The general principle is that the MI of the color masterbatch should be higher than that of the carrier resin.
