Ethylene bis stearamide (EBS) powder is a versatile, high-performance synthetic wax widely used in plastics, rubber, coatings, cosmetics, and other industrial applications as a lubricant, anti-blocking agent, and surface modifier. This fine, white powder is manufactured by reacting stearic acid with ethylenediamine, producing a chemically stable, thermally resistant compound with excellent lubricity and compatibility with a broad range of materials. Its fine particle size, uniform distribution, and consistent quality make it ideal for industrial use, ensuring smoother processing, improved surface finish, and enhanced product performance across multiple applications.

Key Features and Benefits

Exceptional Lubrication: EBS powder reduces friction between polymer chains during extrusion, molding, and calendering, preventing die buildup, blocking, and sticking. It allows for smoother processing, higher efficiency, and consistent material flow.

Anti-Blocking and Release Agent: It minimizes adhesion between sheets, films, coatings, and molded products, ensuring easy demolding, separation, and handling without compromising surface quality.

Thermal Stability: EBS maintains its physical and chemical properties under high-temperature conditions, making it suitable for PVC, polyethylene, polypropylene, and various thermoplastic resins.

Surface Finish Enhancement: The powder produces smooth, uniform surfaces in molded or extruded products, improving gloss, tactile feel, and overall aesthetics.

Wide Applicability: EBS powder is compatible with plastics, rubbers, waxes, coatings, powder coatings, cosmetics, and other industrial formulations, providing multifunctional benefits in diverse manufacturing processes.

Composition and Physical Properties

Chemical Name: Ethylene bis stearamide

Appearance: Fine white powder

Melting Point: 140–145°C

Density: 0.97–1.0 g/cm³

EBS powder is chemically stable, non-toxic, odorless, and safe to handle. Its small and uniform particle size ensures optimal dispersion within polymer matrices, enhancing lubrication, flow, and processing performance while reducing the risk of defects or irregularities. It can also act as a texturizing agent, slip modifier, or anti-caking additive in cosmetic formulations, offering multifunctional benefits for a variety of applications.

Applications

Plastics: Enhances flow and processing in PVC, PE, PP, and other thermoplastics, reduces die build-up, and improves molded product surface finish.

Rubber Compounds: Acts as a processing aid, release agent, and anti-blocking additive during molding and extrusion of natural and synthetic rubbers.

Powder Coatings: Improves flow, surface gloss, and prevents sticking during the curing process, leading to high-quality coated finishes.

Cosmetics: Used as a slip agent, texture enhancer, and anti-caking additive in powders, creams, lotions, and other personal care products.

Wax and Lubricant Blends: Enhances slip, stability, and processability in waxes, greases, and industrial lubricants.

Usage Instructions
EBS powder can be incorporated directly into polymers, rubbers, coatings, or cosmetic formulations during mixing, extrusion, or compounding. Typical addition levels range from 0.5% to 3% by weight, depending on the application and desired effect. For plastics, it is typically added during melt processing to improve lubrication and surface finish. In cosmetics or coatings, it can be blended with powders, creams, or lotions to improve texture, reduce caking, and enhance spreadability.

Storage and Handling
Store EBS powder in a cool, dry, and well-ventilated area, away from moisture and direct sunlight. Keep containers tightly closed to prevent contamination. Avoid inhalation of dust during handling, and use appropriate personal protective equipment. Under proper storage conditions, the shelf life is typically 24 months.

Benefits for Manufacturers
Incorporating EBS powder into industrial formulations provides manufacturers with a wide range of advantages. It enhances processing efficiency, reduces defects, improves product appearance, and contributes to consistent production quality. Its multifunctional properties allow it to serve as a lubricant, anti-blocking agent, and surface modifier simultaneously, making it a cost-effective and reliable additive for modern manufacturing processes.

Conclusion
Ethylene bis stearamide powder is an essential high-performance additive for plastics, rubbers, coatings, cosmetics, and other industrial applications. Its exceptional lubricity, thermal stability, anti-blocking properties, and broad compatibility make it a versatile and indispensable component in modern production environments. By using EBS powder, manufacturers can achieve smoother processing, improved surface finish, reduced defects, enhanced product aesthetics, and consistent performance across multiple applications, ensuring higher efficiency, lower waste, and better overall product quality.
