Abstract

A continuous, industrially scalable process known as solid-state shear pulverization (SSSP) was used to disperse colorant materials in a polymer matrix, which was followed by melt-processing (MP). This novel two-step technique was shown to overcome several issues often encountered with conventional MP, which include the elimination of "swirl patterns" and color shifting. We also show through this two-step SSSP/MP procedure that we can achieve a similar color to a part made only by MP by using approximately 25% less colorant. Finally, we demonstrate that the two-step SSSP/MP technique can be used to blend primary and secondary colorant materials in order to create uniform secondary and tertiary colors, a process that cannot be easily achieved via MP only.
