Polyethylene wax has been widely used in the production of plastic masterbatch due to its superior performance and economical price. However, given the various quality grades of polyethylene wax in the market, it is necessary for users to effectively grasp the quality grades of pe wax used in relevant products during use, in order to avoid neglecting the quality requirements of relevant products while pursuing economic benefits.

Low molecular weight polyethylene, commonly known as polyethylene wax, refers to polyethylene with a molecular weight of around 1000-5000. According to different manufacturing methods, polyethylene wax can be divided into two types: polymerization type and cracking type. The former is formed by the polymerization of small molecule olefins through high and low pressure methods, while the latter is produced by the thermal cracking of polyethylene. Due to different molecular structures, polyethylene waxes can be divided into two types: high density and low density, which mainly depends on the number and length of branch chains in their molecules. At present, there are many domestic and foreign manufacturers producing polyethylene wax. Foreign manufacturers generally use polymerization method for production, while domestic manufacturers use cracking method for production.

Adding polyethylene wax to the color masterbatch helps to wet the pigment, reduce the particle size of the pigment, accelerate the wetting between the carrier resin and the pigment, increase their previous affinity, thereby improving the compatibility between the pigment and the carrier resin, and to some extent, improving the dispersion level of the pigment. In addition, polyethylene wax can also improve the flowability of masterbatches, increase production rates, and improve product processing performance, especially for polyethylene hydrocarbon color masterbatches.

In the color masterbatch industry, dispersants are generally used to improve the dispersion level of pigments. Dispersants can moisten pigments, reduce pigment particle size, thereby strengthening the affinity between pigments and carriers, improving the coloring effect of pigments, enhancing the carrier’s carrying capacity, and obtaining highly intelligent thick color masterbatches.
