Twin screw compounding improves dispersion of color masterbatches
Color masterbatches are difficult to manufacture due to difficulties faced in dispersion of colourants. Organic colourants are particularly difficult to disperse in the polymer matrix in non-polar polymers such as PE and PP. Dispersion, however, could be easier in PVC or PS. Wetting agents do improve dispersion but organic colourants are difficult despite incorporation of wetting agents. PE and PP use wax as dispersion agents, which after melting, wets colorants and reduces the agglomeration of colorants which have very fine particle size distribution.
