Polyethylene wax is a kind of ultra-low molecular weight polyethylene, which is generally divided into oligomer wax, pyrolysis wax, polymerization wax and blend wax. Domestic production of oligomeric wax, foreign main production of other cracking wax, polymerization wax and blending wax. The performance of the polymerized wax is theoretically superior to that of the cracked wax, depending on the compatibility of the product.

Polyethylene wax has stable chemical properties, smooth hand feeling, good wear resistance and high hardness. Its different addition methods and proportions can give different gloss changes to the mixed system, and it is widely used.

1. Application of polyethylene wax in waterborne coatings. After adding emulsifier to polyethylene wax to make emulsion, it can be added to acrylic resin to improve its hydrophilicity to a certain extent, and play the role of non-slip, anti-adhesion and stain resistance.

2. Application of polyethylene wax in road coatings. The polyethylene wax can properly control the gloss of the coating film and give the coating film a solemn feeling. It has poor compatibility with cellulose, high hardness, and high melting point, so it should be made into a toluene dispersion and then added to the paint. In use, light migrates to the surface of the coating film and then to the polyethylene wax powder particles. Through the refraction and diffusion of the powder particles, the reflection of the light projected on the coating surface in the same direction is weakened, and the extinction effect is achieved. Different particle size and variety of polyethylene wax matting effect is also different. From completely maintaining gloss to deep matting, the amount can be adjusted as needed to achieve the desired effect.

3. Application of masterbatch. A large amount of toner is used in the plastics processing industry. Since the toner is difficult to disperse in a resin matrix, the toner and the resin are generally formulated into a master batch having a high toner concentration. Polyethylene wax has good compatibility with toner, so it is easy to wet the pigment, and can penetrate into the internal pores of the pigment aggregate, weaken the cohesion, and make the pigment aggregate more easily broken under the action of external shear force. The newly formed particles can be quickly wetted and protected, and can be used as a dispersant for various thermoplastic resins, a filler masterbatch, and a lubricating dispersant for degraded masterbatch. The polyethylene wax can also provide the same charge on the surface of the pigment particles. Based on the principle of same-sex repulsion, the particles will not attract or aggregate each other, so as to achieve uniform dispersion of the pigment. In addition, polyethylene wax can also reduce the viscosity of the system and improve fluidity. Therefore, the addition of polyethylene wax in the production of masterbatch can improve production efficiency, increase production, and stabilize the dispersion effect.

4. Application in plastic dyeing.polyethylene waxIt can be used as a pigment dispersant for plastic dyeing. When dyeing plastics, the degree of dispersion of the pigment has a great influence on the quality of the dyed product. Therefore, the pigment should be mixed with a mixer and uniformly dispersed in a dispersant in advance to be used as a colorant and mixed into the plastic for dyeing. As a dispersant, polyethylene wax has good compatibility and heat resistance with plastics, is well mixed with pigments, is easy to break, and does not affect the color of the pigment and the color of the product. The addition of polyethylene wax can make the surface of the pigment particles charged, based on the principle of same-sex repulsion, the particles will not attract or aggregate each other, so as to achieve the stability of the pigment.

5. Application of polyethylene wax in paraffin wax. Polyethylene wax can be used as a paraffin modifier, which has good compatibility with paraffin and microcrystalline paraffin, and can improve the melting point, water resistance, moisture permeability and hardness of paraffin. In addition, due to its good electrical properties, it can also be used as an insulation wax modifier for electrical appliances such as capacitors and transformers.

  polyethylene waxIt is widely used, but there is still a lot of room for development in the application of PVC profiles, plastic pipe fittings, plastic molding printing inks, coatings, floor wax, car wax, wax polish and other products, and research and development are still needed to obtain more applications.
