Understanding Masterbatch
Definition and Composition
Masterbatch is a solid or liquid additive used for coloring plastics (color masterbatch) or imparting other properties to plastics (additive masterbatch). It is a concentrated mixture encapsulated during a heat process into a carrier resin, which is then cooled and cut into granular shapes. This process ensures the homogeneous distribution of pigments and additives within the carrier resin, facilitating easy incorporation into the final polymer during the molding or extrusion process.
Types of Masterbatch
Masterbatch can be categorized into several types based on its function and composition. The primary categories include color masterbatch, additive masterbatch, and filler masterbatch. Each type serves a specific purpose in modifying the properties of the base polymer to meet desired specifications.
Color Masterbatch
Role in Plastics Coloring
Color masterbatch is specifically formulated to impart color to plastic products. It contains high concentrations of pigments or dyes dispersed within a carrier resin compatible with the base polymer. This ensures that the color is evenly distributed throughout the plastic material, resulting in consistent and uniform coloration. The utilization of color masterbatch allows manufacturers to produce plastics in a wide spectrum of colors, enhancing product aesthetics and brand identity.
