Polyethylene Wax: A Versatile Additive in Polymer Processing
Polyethylene wax (PE wax), also known as high molecular weight polyethylene wax, is widely used due to its excellent properties. It offers cold resistance, heat resistance, chemical resistance, and abrasion resistance. In normal production, PE wax is directly added as an additive to polyolefin processing, enhancing product gloss and processability. As a lubricant, it exhibits stable chemical properties and good electrical performance.Get more news about Polyethylene Wax,you can vist our website!
Applications of Polyethylene Wax
Color Masterbatches and Filler Masterbatches: PE wax is commonly used as a dispersant in color masterbatches for polyolefins. It has excellent compatibility with polyethylene, polypropylene, and PVC resins, providing both external and internal lubrication.
PVC Profiles, Pipes, and Composite Stabilizers: In the processing of PVC profiles, pipes, and fittings, PE wax acts as a dispersant, lubricant, and brightener. It improves plasticization, toughness, and surface smoothness.
Inks: PE wax enhances wear resistance, dispersion of pigments, and prevents settling. It serves as a matting agent, providing gloss and a three-dimensional effect.
Floor Waxes, Car Waxes, and Polishes: PE wax is widely used in the production of various wax products, increasing softening points, strength, and surface gloss.
Cable Insulation Materials: As a lubricant, it facilitates filler dispersion, improves extrusion rates, and eases mold release.
Hot-Melt Adhesives: PE wax is used in various hot-melt adhesives, thermosetting powder coatings, road marking paints, and more. It acts as a dispersant and provides gloss and a three-dimensional effect.
Rubber Processing: PE wax enhances filler dispersion, extrusion rates, and mold flow, resulting in improved surface gloss and smoothness after demolding.
Cosmetics: PE wax provides gloss and a three-dimensional effect in cosmetic formulations.
Injection Molding: It reduces machine power requirements and enhances surface gloss in injection-molded products.
Production Process
PE wax is derived from high molecular weight polyethylene through a series of depolymerization reactions. The critical step is the depolymerization process, which occurs within a closed reactor.

European Materials
European PE waxes (such as EUROCERAS) are functional waxes that can effectively replace natural montan wax. They find applications in color masterbatches, PVC, and modified engineering plastics.
