Liquid color is the uniform dispersion of colorant and/or additives in a liquid carrier/surfactant mixture, used for imparting color or modifying other properties in plastics or rubber. Being liquid, the dispersion can be accurately metered directly into injection molding machines or extruders by in-line metering systems, which help overcome many of the disadvantages of solid additive and colorant concentrates.
Advanced liquid dispersions are engineered for optimized polymer compatibility.
