What is the effect of polyethylene wax on the dispersion state of pigments?

Polyethylene wax is widely used in the production process of plastic masterbatch due to its superiority in performance and economical price. However, in view of the difference of various quality grades of polyethylene wax on the market, it is necessary for users to grasp the quality grade of polyethylene wax used in related products in the process of use, so as to avoid ignoring related products while pursuing economic benefits. quality requirements.

Low molecular weight polyethylene is generally called polyethylene wax, which refers to polyethylene with a molecular weight of about 1000~5000. According to the different manufacturing methods, polyethylene wax can be divided into two types: polymerized and cracked. The former is obtained by the polymerization of small molecular olefins by high and low pressure methods, and the latter is obtained by thermal cracking of polyethylene. Due to different molecular structures, polyethylene waxes can be divided into high and low density types, which mainly depend on the number and length of branched chains in their molecules. At present, there are many polyethylene wax manufacturers at home and abroad producing polyethylene wax. Foreign manufacturers generally use the polymerization method to produce them, while domestic manufacturers use the pyrolysis method to produce them.

The addition of 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 of the pigment and the carrier resin, to a certain extent to improve the dispersion level of pigments. In addition, polyethylene wax can also improve the fluidity of masterbatch, increase yield and improve product processing performance, especially polyethylene hydrocarbon masterbatch.

In the masterbatch industry, dispersants are generally used to improve the dispersion level of pigments. The dispersant can wet the pigment and reduce the particle size of the pigment, thereby enhancing the affinity between the pigment and the carrier, improving the coloring effect of the pigment, improving the carrying capacity of the carrier, and obtaining a high-intelligence concentrated color masterbatch.
