A masterbatch is a concentrated mixture of pigments and / or additives blended and extruded together in a carrier matrix, such as resin or wax, that is used to add these mixed additives to a final plastic product. The additives may be used for colouring (a "colour masterbatch") or for imparting other properties (an "additive masterbatch"). The typical alternative to using a masterbatch is to compound the plastic from raw undiluted additives.

== Manufacturing plastics from masterbatches == The general process for the manufacture of masterbatches involves first identifying and weighing the needed pigments and/or additives, then mixing the pigments or additives with a carrier resin or polymer. Finally, the concentrated mixture is extruded, cooled and formed into granules, powders, or other masterbatch vehicles and the final product is bagged.
