Features and Applications of PE WAX

Ⅰ. Polyethylene wax properties

PE wax (tissuemat E) is a chemical material, whose color is white small beads/sheets, formed by ethylene polymer rubber processing agent, which has the characteristics of high pe wax melting point, high hardness, high gloss, and snow-white color.

Ⅱ. The Production Process of PE Wax

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

Ⅲ. Uses of PE Wax in Coatings

PE wax is a low molecular weight polyethylene homopolymer or copolymer widely used in coatings. The so-called wax means that the polymer finally floats in the form of microcrystals in the surface layer of the paint and plays a role similar to paraffin but more diverse and practical than paraffin manufactured by the paraffin wax manufacturer.

The main functions of PE wax in solvent-based coatings are: 

Matting, anti-scratch, anti-abrasion, anti-polishing, anti-marking, anti-adhesion, anti-sedimentation, thixotropy; good lubricity and processability; metallic pigment positioning.

The working principle of PE wax: 

The polyethylene wax melting point is relatively high. PE wax dissolves in solvent at high temperature (about 100-140 ℃), precipitates when cooled to room temperature, and exists in the coating in the form of microcrystals. Because of its thixotropy, it is beneficial to the storage of the coating, and after the coating is applied, it can migrate to the surface layer of the coating film during the volatilization process of the solvent, and finally form a "waxed" surface layer with other components of the coating.

The effect of PE wax depends on the following factors: 

The variety and specification of PE wax, the affordable pe wax price, the final particle size, the ability to migrate to the surface of the coating film and the composition of the coating, the polyethylene wax properties of the substrate to be coated, and the method of construction and application.

Ⅳ. Other uses of PE wax

1. Concentrated color masterbatch and filler masterbatch

It is used as a dispersant in the processing of color masterbatches, 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, composite stabilizers

It is used as dispersant, lubricant and brightener in the molding process of PVC profiles, pipes, pipe fittings, PE.PP, to enhance the degree of plasticization, improve the toughness and surface smoothness of plastic products, and be widely used in the production of PVC composite stabilizers. 

3. Ink

PE wax has good light resistance and chemical properties, which can be used as a carrier for pigments to improve the abrasion resistance of paints and inks, improve the dispersibility of pigments and fillers, and has good anti-settling effect. It can also be used as a flattening agent for paints and inks, so that the products have good gloss and three-dimensional effect.

4. Wax products

PE wax is widely used in the production of various wax products such as floor wax, car wax, glazing wax, candles, and crayons to improve the softening point of wax products and increase their strength and surface gloss.

5. Cable material

PE wax can be used as a lubricant for cable insulation materials, which can enhance the diffusion of fillers, increase the extrusion rate, increase the mold flow, and facilitate demolding.

6. Hot melt products

It is used for various hot melt adhesives, thermosetting powder coatings, road marking paints, and scribing paints as a dispersant. The industrial wax has a good anti-settling effect and makes the products have good gloss and three-dimensional effect.

7. Rubber

As a rubber processing aid, PE wax can enhance the diffusion of fillers, increase the extrusion rate, increase the mold flow, facilitate demolding, and improve the surface brightness and smoothness of the product after demolding.

8. Cosmetics

PE wax enables the product to have good luster and three-dimensional effect.

9. Injection molding

It can save machine power, improve the lubrication and enhance the surface gloss of the product
