Calcium carbonate (CaCO3) filler masterbatch (or filler master batch) is a concentrated mixture of calcium carbonate and other additives encapsulated during a heat (mainly extrusion) process into a carrier polymer resin which is then cooled and cut into granules (pellets) making CaCO3 masterbatch a solid additive for plastics. Since common CaCO3 MB was originally intended for filling plastics to replace a part of expensive carrier resin it is often called filler masterbatch or filler additive.
