Ethylene Bis Stearamide (EBS) is a synthetically produced waxy solid, derived from the reaction of stearic acid and ethylenediamine. Its molecular structure is lipophilic (oil-attracting) but insoluble in water. This characteristic makes it a highly effective additive in various industrial fields, with primary functions including lubrication, release, anti-blocking, and surface modification.

Polyethylene wax (PE wax), a low molecular weight polyethylene, is primarily produced through three industrial methods: Direct Synthesis, Cracking (or Degradation), and By-product Purification. Each method differs in its raw materials, process principles, and final product characteristics.

Seasonal changes require manufacturers using polyethylene wax to have the awareness to dynamically adjust their processes. A formula and process parameters perfected in winter, if applied directly in summer, will likely cause problems. Strictly monitoring the actual temperature during the production process, rather than relying solely on set values, is the key to ensuring that polyethylene wax performs optimally in any season

This article explains how the molecular weight of polyethylene wax decisively influences its melting point and viscosity. It classifies PE wax into low, medium, and high molecular weight types, detailing their core characteristics and providing a clear selection guide to help you choose the right grade for plastics processing, coatings, inks, hot-melt adhesives, and other applications requiring lubrication, matting, dispersion, or abrasion resistance.

Hot melt adhesive caking refers to the phenomenon where the adhesive in hot melt glue sticks or glue guns hardens, solidifies, and loses fluidity, becoming rigid like a solid block and failing to melt or function properly. While hot melt adhesive caking is indirectly related to polyethylene wax (PE wax), the wax itself is not the direct cause. Instead, PE wax is a key additive in hot melt adhesive formulations, and its properties or improper dosage may exacerbate caking issues.
