Polyethylene wax (PE wax), also known as polymer wax or polyethylene wax for short. It is widely used because of its excellent cold resistance, heat resistance, chemical resistance and abrasion resistance. In normal production, this part of wax can be directly added to polyolefin processing as an additive, which can increase the gloss and processing performance of the product. As a lubricant, it has stable chemical properties and good electrical properties. Polyethylene wax has good compatibility with polyethylene, polypropylene, polyvinyl acetate, ethylene propylene rubber, and butyl rubber. It can improve the fluidity of polyethylene, polypropylene, ABS and the mold release of polymethyl methacrylate and polycarbonate. Compared with PVC and other external lubricants, polyethylene wax has stronger internal lubrication.

Polyethylene wax is a chemical material, in which the color of polyethylene wax is white small beads/sheets, which are formed by ethylene polymer rubber processing agent, which has a high melting point, high hardness and glossiness. High, white color and other characteristics.

Polyethylene wax is a low molecular weight polyethylene homopolymer or copolymer widely used in coatings. The so-called wax means that the polymer is finally floating in the form of microcrystals in the surface layer of the paint, which is similar to paraffin but has more diverse and practical effects than paraffin.

What is the composition of PE wax?

The main functions of polyethylene wax in solvent-based coatings are: matting, anti-scratch, anti-wear, anti-polishing, anti-marking, anti-adhesion, anti-sedimentation, thixotropy; good lubricity and processability; metal pigment positioning sex.

The working principle of polyethylene wax is as follows: polyethylene wax dissolves in solvent at high temperature (about 100-140°C), and precipitates out when cooled to normal temperature, and exists in the coating in the form of microcrystals, because of its thixotropy. It is beneficial to the storage of the paint, and after the paint is applied, it can migrate to the surface layer of the paint film during the solvent volatilization process, and finally form a “waxy” surface layer with other components of the paint.

The effect of polyethylene wax depends on the following factors: the variety and specification of polyethylene wax, the final particle size, the ability to migrate to the surface of the coating film, the composition of the coating, the nature of the coated substrate, and the construction and application method.

Production process of polyethylene wax

Cracked polyethylene wax is made by using high molecular weight polyethylene as the main raw material, adding other auxiliary materials, and going through a series of depolymerization reactions. Depolymerization reaction is the most critical part in the production of polyethylene wax, and the whole process of depolymerization reaction should be carried out in a closed reactor.

Application of Polyethylene Wax

1. Concentrated color masterbatch and filling masterbatch. As a dispersant in the processing of color masterbatches, it is widely used in polyolefin color masterbatches. It has good compatibility with polyethylene, polyvinyl chloride, polypropylene and other resins, and has excellent external and internal lubrication.

2. PVC profiles, pipes, and compound stabilizers are used as dispersants, lubricants, and brighteners during the molding process of PVC profiles, pipes, pipe fittings, and PE.PP to enhance the degree of plasticization and improve the toughness and surface smoothness of plastic products. . And widely used in the production of PVC compound stabilizer.

3. The ink has good light resistance and chemical properties, can be used as a carrier of pigments, can improve the wear resistance of paints and inks, improve the dispersion of pigments and fillers, has good anti-sedimentation effect, and can be used as a flatting agent for paints and inks. The finished product has good luster and three-dimensional effect.

4 Wax products Widely used in the production of various wax products such as floor wax, car wax, glazing wax, candles, crayons, etc., to increase the softening point of wax products, increase their strength and surface gloss.

5. Cable material Used as a lubricant for cable insulation materials, it can enhance the diffusion of fillers, increase the extrusion molding rate, increase the flow rate of the mold, and facilitate demoulding.
