PE Wax powder (polyethylene wax) is a polyethylene product with a low molecular weight. It has excellent heat resistance, wear resistance and good dispersibility. In various thermal processing processes, it is often used as a lubricant, release agent, dispersant or gloss additive. Due to its high thermal stability and stable chemical properties, PE wax is widely used in many industrial fields such as plastic processing, rubber products, inks, coatings, hot melt adhesives and textiles. It can not only improve processing performance, but also enhance product surface quality and mechanical properties. Here are the five main applications of polyethylene wax powder !

Promote Lubrication and Dispersion of Masterbatch
During the production process of masterbatch, pigment particles will “agglomerate”. PE wax powder can be adsorbed on the surface of pigment particles, creating barriers between pigment particles. This allows the pigment particles to be evenly dispersed.
During mixing and granulation, polyethylene wax can reduce the friction between the material and the screw and barrel. Maintain a good dispersion state of pigment particles, thereby improving the quality of masterbatch.
For some organic pigments, their solubility in some plastic resins is not good, and polyethylene wax can help these pigments disperse better in the resin. It plays a bridge role between pigments and resins.
Improve PVC Processing Performance
At the processing temperature of PVC, polyethylene wax can maintain good thermal stability. The processing temperature range of PVC is relatively narrow, and polyethylene wax can perform well within this temperature range. It will not decompose or fail due to temperature changes, making the torque of PVC more stable during processing.
In addition, PE wax powder also helps improve the fluidity of PVC during extrusion processing. It allows PVC to be extruded more smoothly in the processing equipment. It prevents PVC melt from sticking to the equipment, reduces surface defects of the product, and helps to extend the service life of the equipment.
Promote the Fluidity of Powder Coatings
During the storage of paint, pigments and other solid particles tend to settle at the bottom of the container.
can prevent this from happening through steric hindrance and adsorption.
Polyethylene wax can improve the wear resistance and scratch resistance of the paint. After the paint dries, polyethylene wax forms a relatively hard protective film on the surface of the coating.
Polyethylene wax can enhance the waterproofness and anti-fouling properties of the paint to a certain extent. On the surface of the coating, the presence of polyethylene wax can make water droplets difficult to penetrate, forming water beads rolling on the surface.
Improve the Wear Resistance of Ink
Polyethylene wax will migrate to the surface of the ink film during the drying process of the ink. For example, in book printing, when books are repeatedly turned over, friction will occur between the papers. The protective film formed by polyethylene wax on the surface of the ink reduces friction.
Polyethylene wax can be used in ink as an anti-sticking agent. During the printing process, especially in high-speed printing or when the ink dries slowly, the printed matter is prone to adhesion. It can reduce the viscosity of the ink, so that the ink maintains an appropriate drying speed and surface state during the drying process, and prevent the printed matter from sticking.
Polyethylene wax can adjust the fluidity of the ink. It can avoid the accumulation of ink or uneven transfer, thereby improving the printing quality.
Polyethylene wax can affect the gloss and texture of the ink. When the ink dries, polyethylene wax can form a smooth film on the surface of the ink to improve the gloss of the ink.
Improve the Demoulding Property of Rubber
In the vulcanization molding process of rubber products, polyethylene wax plays a key role in demolding. After the rubber is molded in the vulcanization mold, it tends to adhere tightly to the mold surface, which makes demolding difficult. Polyethylene wax can form a layer of isolation film between the rubber and the mold.
Polyethylene wax can improve the flexibility of rubber. Rubber seals plasticized with polyethylene wax can better adapt to different sealing environments. For example, when subjected to a certain degree of extrusion or stretching, it can still maintain good sealing performance and effectively prevent the leakage of liquid or gas.
Polyethylene wax can also reduce the friction between rubber and compounding agents, making the mixing process smoother. Thereby reducing energy consumption during mixing and improving production efficiency.
Conclusion
In summary, PE wax powder plays a vital role across multiple industries due to its excellent thermal stability, lubrication, and dispersibility. Its versatile performance continues to drive innovation in plastics, coatings, rubber, and beyond, making it an essential additive for modern industrial applications.
