Color Master Batch and Additive Master Batch

Master batch, also called concentrate, is a term used in the plastics industry to denote a pelletized plastic material containing highly loaded pigments and/or additives that are used in a polymer system to change the final color and/or properties of a plastic part. There are basically two kinds of master batches – color master batch, and additive master batch. Color master batches are used by the plastic converters to give various colors to their plastic products. Additive master batches are also used by the plastic converters to provide their products with special properties like antioxidant, antistatic, conductive, flame retarding and ultra-violet stabilizing properties.
