A color masterbatch is a commonly used additive in the processing of polymer materials, primarily functioning to provide a wide range of color effects for plastics, rubber, and other products. Through a specific process, pigments or dyes are evenly mixed with a resin carrier and processed into granular form by a granulator, which is the color masterbatch. It not only significantly enhances the aesthetics of products but also improves their physical properties to some extent, such as weather resistance and aging resistance. The use of color masterbatches is simple and convenient; just mix them with the raw materials in a certain proportion during the plastic processing, making them widely used in various fields such as plastic packaging, automotive parts, and electronic product casings.
