Master Batches

Masterbatch is a solid plastic additive used to color or impart other properties to plastics. A concentrated mixture obtained by the distribution of colours and additives into a polymer carrier by heat treatment and in-particularly a high shear mixing extruder is called masterbatch.

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.
