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.
