Ethylene Bis Stearamide (EBS) is a synthetic wax widely used in plastics, rubber, masterbatch, coatings, and other industrial products. It works as a lubricant, dispersing aid, and mold release agent in many formulations. In addition, it can help reduce sticking and improve the handling of selected materials.
Manufacturers value EBS wax for its high melting point, low water solubility, and useful surface properties. As a result, it supports several production methods, including extrusion, injection molding, and compounding.
However, product performance depends on the grade, particle size, dosage, and final formulation. Therefore, buyers should compare technical data before selecting a product.
This article explains the properties, production methods, applications, major manufacturers, and sourcing factors of Ethylene Bis Stearamide. It also explores its role in industrial manufacturing and the Turkish chemical market.
1. What Is Ethylene Bis Stearamide?
Ethylene Bis Stearamide is a synthetic fatty acid bis-amide made from stearic acid and ethylenediamine. It belongs to a group of materials known as amide waxes.
The chemical formula is C₃₈H₇₆N₂O₂, while its molecular weight is approximately 593.0 g/mol. In addition, its CAS number is 110-30-5.
The material usually appears as a white or slightly off-white powder, bead, or granular solid. Furthermore, it has a relatively high melting point compared with many common fatty acid lubricants.
Because of these features, manufacturers use EBS to help control friction and improve processing in selected materials.
For example, plastic producers add it to certain polymer compounds, while pigment makers use suitable grades to support dispersion. As a result, the same chemical can serve several functions across different industries.

3. Main Properties and Benefits of EBS Wax
Ethylene Bis Stearamide offers several useful properties in industrial production. However, each application requires a suitable grade and dosage.
Internal and External Lubrication
EBS can act as both an internal and external lubricant in selected polymer systems.
Internal lubrication helps reduce friction within the material during processing. Meanwhile, external lubrication helps limit friction between the material and equipment surfaces.
As a result, suitable formulations may achieve smoother processing and improved material flow.
Mold Release Performance
Some molded products can stick to equipment surfaces. Therefore, manufacturers use release agents to help remove finished parts.
EBS wax can support mold release in selected plastics and rubber products. In addition, it may help reduce surface defects caused by sticking.
Pigment and Filler Dispersion
Pigments and fillers must spread evenly throughout a formulation. Otherwise, the finished product may show uneven color or inconsistent performance.
EBS can help improve dispersion in suitable systems. Consequently, manufacturers may achieve more uniform blends and better processing results.
Anti-Blocking Properties
Some films, granules, and molded products tend to stick together during handling or storage.
For this reason, suitable EBS grades can serve as anti-blocking additives. However, the effect depends on the base material and operating conditions.
Surface Quality
EBS may help improve surface smoothness and appearance in selected formulations.
Furthermore, suitable grades can support consistent processing and reduce unwanted friction.
Nevertheless, manufacturers should test the final product because excessive dosage may affect adhesion, printing, or other surface properties.
4. Ethylene Bis Stearamide Uses Across Industries

For example, certain polyamide, polycarbonate, and other technical compounds may benefit from improved lubrication or release.
In addition, high-temperature processing requires careful grade selection. Therefore, manufacturers should confirm thermal behavior under their actual production conditions.
6. EBS Wax in Masterbatch, Pigments and Coatings
Masterbatch producers need to distribute pigments and fillers evenly within a polymer carrier.
However, poor dispersion can create color differences, visible particles, and processing problems.
EBS wax can help improve pigment wetting and distribution in suitable formulations. As a result, it may support more uniform color and better processing.
Color Masterbatch
Color masterbatch contains concentrated pigments within a carrier resin.
Therefore, producers need additives that help distribute pigment particles during mixing.
Suitable EBS grades can support this process. In addition, they may help reduce friction during compounding.
Filler Masterbatch
Mineral fillers can affect material flow and mixing behavior.
For this reason, manufacturers may use EBS alongside other processing aids.
However, performance depends on filler type, loading, carrier resin, and equipment.
Paints and Powder Coatings
Selected coating systems use amide waxes to help control dispersion and surface properties.
For example, EBS may support pigment distribution and surface performance in suitable coating formulations.
Furthermore, fine-particle grades can offer different behavior from larger beads.
Therefore, coating manufacturers should evaluate particle size, compatibility, and the final finish before choosing a grade.
Printing Inks
Ink producers need even pigment distribution and controlled surface behavior.
EBS can serve as a functional additive in selected ink systems. In addition, it may help improve slip and reduce unwanted surface friction.
Nevertheless, the final effect depends on the binder, solvent system, and printing method.
7. Ethylene Bis Stearamide in Rubber and Other Materials
EBS also serves industries beyond conventional plastics.

Powder Metallurgy
Metal powder processing requires controlled friction during pressing and shaping.
EBS can serve as a lubricant in selected powder metallurgy systems. As a result, it may help reduce friction during compaction and part release.
Nevertheless, manufacturers must consider lubricant removal and the later heat treatment process.
Foundry Applications
Some resin-bonded foundry systems use wax-based additives to support processing and release.
For example, EBS may serve as a lubricant in selected shell-molding formulations.
However, the right grade and dosage depend on the resin and operating conditions.
Adhesives and Asphalt Products
Certain adhesive systems use EBS for anti-blocking and processing control.
Likewise, some modified asphalt products use amide waxes as functional additives.
Nevertheless, these applications require formulation-specific testing. Therefore, buyers should confirm performance rather than assume that one grade suits every use.
8. How Is Ethylene Bis Stearamide Produced?
Manufacturers commonly produce Ethylene Bis Stearamide through a reaction between stearic acid and ethylenediamine.
During the reaction, the materials form amide bonds and release water.
The simplified reaction is:
2 Stearic Acid + Ethylenediamine → Ethylene Bis Stearamide + 2 Water
However, commercial production requires careful control of temperature, reaction conditions, and raw material quality.
After the reaction, producers may process the material into powder, beads, or granules.
In addition, some manufacturers offer different particle sizes for specific applications.
The production method and raw materials can affect several quality points:
- Melting range
- Acid value
- Amine value
