Colorants added in the mixing phase of the manufacturing process can generate transparent, translucent or opaque colors. Liquid colorants will produce transparent, translucent and tinted color. Solid colorants are better for generating highly opaque colors—including metallic, pearlescent and glow-in-the- dark colors—or patterns and effects, like marbling, wood or camouflage.

Since masterbatch coloring needs to be corrected each time, the color properties of PCR change. Calculate color corrections to meet a target color 3. Define PCR color specification limits and find PCR grades to achieve a target color 4.

Design times can be less than three days for colorants. There are significant revenue opportunities generated from the combined color and additive technology strengths of the two legacy companies.
