Problems solved by technology

Color masterbatches are divided into general-purpose color masterbatches and special-purpose color masterbatches. General-purpose color masterbatches can be applied to other resins except their carrier resins, but the predictability of the coloring effect is poor, which affects the strength and toughness of plastic products. High requirements for pigments lead to high cost; and the special color masterbatch is selected as the carrier of the same or good compatibility as the user-specified plastic products. Compatibility, uniform coloring, stability, and can improve the quality of plastic products. Therefore, at present, special color masterbatches are generally used in plastic products to improve color and performance.
