During the processing of color masterbatches, the addition of products such as polyethylene wax and amide wax can improve processing performance, effectively wet the pigment particles, stabilize the dispersion, prevent the re-aggregation of pigment particles, and enhance the coloring strength of the products. In filled masterbatches, they have good coating and wetting effects on inorganic powders, improving processing performance, having good lubrication in the early, middle and late stages, and resulting in good surface gloss of the downstream products.
