Coloring polymers in any process gives a degree of freedom and flexibility that’s not possible with pre-colored polymers. Why it’s a mistake: Solid and liquid colorants each have certain applications where they make the most sense in terms of coloring effects, efficiency, and results. There’s actually also a third potential pitfall here: A processor who purchases one type of equipment (liquid-color dosing or solid-color feeders) may wrongly believe their operation cannot accommodate the other type of color technology.

From creation to product delivery, this service speeds up every step of the color journey,” explains John Van Hulle, president, Global Color, Additives and Inks, PolyOne Corporation. Rapid Color Design and Choice: Colors can be easily created using existing standards, spectrophotometer or colorimeter inputs or the software’s built-in color design tools. These range from creating colors remotely through one of PolyOne’s facilities, to installing this color development technology in-house for full control and maximum color development speed.

Understanding and addressing the challenges of choosing and using smaller quantities of colorants Avient has introduced a special liquid color production system that could be a good fit if you are ordering small lots of colorant. It also allows for batch-to-batch consistency to address color variations.
