Ethylene Bis-Stearamide (EBS) is a highly effective synthetic wax with a chemical formula of C38H76N2O2 and CAS number 110-30-5. It is characterized by its waxy white solid form, often found as a powder or beads. EBS is derived from the reaction of ethylenediamine and stearic acid, endowing it with a unique molecular structure that facilitates its wide range of industrial applications.

The chemical properties of EBS are central to its utility. It is insoluble in water but soluble in hot organic solvents, exhibiting excellent lubricity, dispersibility, and thermal stability. Its melting point typically ranges from 141-146°C, and it decomposes at temperatures above 250°C. These characteristics make it suitable for use in high-temperature processing environments. The polar amide groups within its molecular structure, coupled with non-polar fatty chains, allow it to act as a highly effective surface-active agent.

EBS is extensively utilized as a lubricant in plastic and rubber processing. It functions as both an internal and external lubricant, reducing melt friction, improving flow properties, and preventing adhesion to processing equipment. This leads to enhanced processability, better surface finish, and increased productivity. As a dispersant, EBS is crucial for achieving uniform distribution of pigments and fillers in masterbatches and coatings, ensuring consistent color and improved material properties.

Furthermore, EBS serves as a highly effective mold release agent, facilitating the easy separation of molded products from their molds. This property is critical in injection molding, extrusion, and other forming processes, improving cycle times and product quality. Its role extends to being an anti-static agent, a nucleating agent for enhancing polymer crystallinity, and a degassing agent in certain polymer systems.

The diverse applications of Ethylene Bis-Stearamide (EBS) underscore its importance as a key additive in industries ranging from plastics and rubber to coatings, inks, and powder metallurgy. Understanding its chemical properties provides insight into its broad utility and its contribution to the performance and manufacturability of a vast array of products.
