PE wax, also known as polypropylene wax, is widely used because of its excellent cold resistance, heat resistance, chemical resistance and wear resistance. In normal production, this part of wax can be directly added to polyolefin processing as an additive to increase the gloss and processability of the product. As a lubricant, it has stable chemical properties and good electrical properties.

What is the use of polypropylene wax?

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

Polypropylene wax is a low molecular weight polyethylene homopolymer or copolymer widely used in coatings. By wax, it is meant that this polymer is then floated in microcrystalline form on the surface of the paint to act like paraffin but with a more diverse and practical effect than paraffin.

When the wax powder in the paint is heated, it melts and disperses in the resin melt. As the film cools, it precipitates out of the resin. Polypropylene wax is widely used, such as ink, leather, engineering plastics, textiles, printing and dyeing, adhesives, release agents and other industries. Characteristics and uses of polypropylene wax:

1. Polypropylene wax is precipitated from the coating melt during the film forming process of powder coating, forming fine particles, floating on the coating surface, playing the role of texture, extinction, smoothness, friction resistance, adhesion resistance and stain resistance.

2. texture extinction: when the coating is cooled, the wax particles are precipitated from the coating liquid and migrate to the coating surface, resulting in extinction effect. In powder coatings. Different wax powders have different effects on gloss.

3. The polypropylene wax exists on the surface of the coating in the form of dispersed particles, which reduces the friction coefficient of the coating. When an object hits the surface of the coating, the sliding tendency is greater than the scratching tendency, reducing the friction and polishing tendency, and insisting on low gloss durability.

4. Polypropylene wax enhances the wetting and dispersion of pigment aggregates and improves the coloring strength of the pigment. Adding 1%-3% can increase the coloring strength of the pigment by 10%-30%.

5. Give the coating a comfortable texture, anti-blocking and stain resistance. When foreign matter comes into contact with the coating film, black marks are often left. Wax particles on the surface of the coating can reduce this stain or make the stain easy to wipe off. Polypropylene wax has the characteristics of low viscosity, high softening point and good hardness. It has good dispersion and external lubricity, and can improve the processing and production efficiency of the product.

Polypropylene wax main application scope: can be widely used in the manufacture of masterbatch, granulation, plastic steel, PVC pipe, hot melt adhesive, rubber, shoe polish, leather brightener, cable insulation, floor wax, plastic profiles, printing ink, injection molding and other products.
