As part of the OnColor™ Polymer Colorants masterbatch portfolio, this group of ten masterbatch colorants enables plastic to mimic naturally occurring materials such as stone, marble, and granite. In combination with surface texture and part geometry, these masterbatches give plastic parts the appearance of naturally-occurring materials so that, for example, designers could create a toaster that appears to be carved out of granite. In addition, the masterbatch can contain other performance and/or process-enhancing additives customized to specific needs.
