Abstract
A multi-functional concentrate composition which can be utilized to impart a desired color to a polymeric material and improve the processability thereof. The composition comprises at least one pigment, a blowing or foaming agent, and a binder component which at least allows the polymeric material to be processed at lower pressures than would otherwise be necessary for the same composition without the blowing agent.
