At RTP Company we believe the mode chosen should be a customer decision — we are dedicated to delivering the quality color you expect in the form you are most comfortable working with.
Several methods are available for delivering color for use in molding plastics, including Masterbatches, Cube Blends and Precolors.
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.

RTP Company has standard pallets of popular colors available for both engineering resins and our innovative line of UniColor® masterbatches.
