Essential Guide to Color Concentrates
What Are Color Concentrates?
Historically the most common form of Color Concentrates (a.k.a. masterbatches) are colored plastic pellets. These concentrated colored pellets are typically built to contain 15-50% of specially selected pigments and additives. The remainder of the recipe is a blend of carrier resin, process aids and binders to support consistency within the virgin base resin.
The initial consideration when designing a plastic component is ensuring the base resin AND the color concentrate are suitable for the selected forming process. Common process examples include injection mold, blow mold, injection stretch blow, compression mold and extrusion.
