Plastic color masterbatch is a concentrated mixture of pigments or dyes dispersed in a polymeric carrier resin. It is used to add vibrant and uniform color to plastic products during the manufacturing process. The masterbatch is typically composed of a carrier resin compatible with the base plastic (such as polyethylene or polypropylene) and a high concentration of colorants, usually ranging from 20% to 50%. This formulation allows manufacturers to produce plastics in a wide range of colors with consistent color distribution.

The masterbatch comes in granule or pellet form and is mixed with raw plastic resin during processes like injection molding, extrusion, or blow molding. This method provides better color dispersion, consistent color quality, and easier handling compared to using raw pigments directly. Color masterbatch also offers benefits such as cost savings, enhanced aesthetics, and stable color shades, and it is widely used across industries including packaging, automotive, textiles, and construction.
In summary, plastic color masterbatch is an essential additive that enables efficient, precise, and customizable coloring of plastic products with excellent dispersion and compatibility properties.
