The most common method used by molders, masterbatches consist of concentrated pigments dispersed into a polymer carrier resin. During molding the masterbatch is let down into natural resin as it is feed into the press at a predefined ratio to achieve the desired color. Masterbatches are the most economical method to color plastics and can be provided in small volumes. Depending on the carrier selected, the same masterbatch may be used to color several different resins, or be chosen for maximum compatibility and processing ease.
