What is the difference between a masterbatch and precolored resin?
A masterbatch is pre-dispersed concentrated color that is let down with natural polymer during molding. With a precolor all the polymer is entirely compounded with the proper amount of color and delivered ready-to-use, eliminating metering and dispersion difficulties. A masterbatch offers economic advantages associated with resin purchasing and color obsolescence. Additionally, since masterbatches are not fully compounded most of the polymer used does not exhibit an additional heat history, potentially deteriorating the properties of some polymers.
