The distinct advantages of liquid color for plastic processing are short lead times and economics. Liquid carrier systems are lower in cost than the resin systems they go in. Besides eliminating inventory, the set-up cost and machine time to produce liquid dispersions are less than half of that required to manufacture color concentrate.
Extremely fine dispersions of pigments and dyes can be achieved in liquid color systems through mechanical roll or ball milling. We currently incorporate nano particle dispersions of a wide variety of pigments and additives such as clay, titanium, calcium, talc, bromine and antimony.
Many chemical additives for polymers are liquids. UV inhibitors, anti-stats, lubricants, silicone, heat stabilizers and plasticizers can be metered in their liquid forms. Foaming agents, corrosion inhibitors, and other solid (dry) additives can be put into suspension or solution and may be metered in with or without color.
Peacock Colors has formulas for polycarbonate, polyesters including PET, PETG and BPT, nylon, acetal and PVC as well as the standard liquid color systems for commodity resins.
