Masterbatches are additives used for coloring plastics or for the introduction of other functional additives. They are used in all typical processes of the plastics industry, like injection molding, blow molding, and extrusion. They usually consist of a carrier-polymer, wax as a dispersing agent and pigments. By helping the pigments to disperse very finely, MÜNZING’s high-performance wax dispersing agents increase color strength by up to 5%–15%, reduce pigment consumption and therefore save cost. The very fine particles of our micronized CERETAN® waxes also improve multiple processing aspects like e.g. lowering of the filter pressure, reduction of clogging of filters and enabling a more rapid mixing.
