Filler Masterbatch is a plastic additive made by blending inorganic fillers like calcium carbonate, talc, or silica with a polymer carrier. It enhances mechanical properties—such as stiffness, impact resistance, and dimensional stability—while improving processing efficiency in extrusion, injection, or blow molding. It also reduces shrinkage, warpage, and material costs.

Additionally, filler masterbatch promotes sustainability by lowering virgin plastic use and allows customization of surface finish, color, and opacity. It’s widely used in packaging, construction, automotive, and household applications.
