A Beginner's Guide to Using Ethylene Bis-Stearamide

Ethylene Bis-Stearamide, also commonly known as EBS, is a versatile chemical compound used in a variety of industries such as plastics, textile and paper manufacturing. It is an additive that acts as a lubricant, anti-block and anti-static agent, and a process aid for injection molding and extrusion. In this beginner's guide, we will dive into the properties, benefits, and uses of EBS, as well as share tips on how to properly use it in your manufacturing processes.

Understanding the Properties of EBS

Ethylene Bis-Stearamide is a synthetic wax made by the reaction of ethylene diamine and stearic acid. It has the appearance of a white or light yellow solid, and is typically sold in powder form. EBS has a high melting point of about 140°C, making it a useful additive for high-temperature processing methods like injection molding and extrusion.

EBS is soluble in polar solvents like ethanol and acetone, but insoluble in non-polar solvents like hexane and toluene. It is a non-toxic, non-corrosive, and non-flammable substance, making it a safe additive to use in manufacturing processes.

Benefits of Using EBS in Manufacturing

EBS has several benefits when used as an additive in manufacturing processes. Some of the key benefits include:

- Lubricating properties: EBS acts as a lubricant by reducing friction between the surfaces of materials during processing. This helps to improve the flow and release of materials, resulting in better product quality and reduced waste.

- Anti-block properties: EBS reduces the adhesion between surfaces that can cause materials to stick together. This makes it a useful additive in the production of films, sheets, and other materials that require smooth surface textures.

- Anti-static properties: EBS helps to reduce static electricity buildup in materials, which can cause issues like dust buildup, product contamination, and electrical shock hazards.

- Processing aid: EBS acts as a processing aid by improving the processing speed and efficiency of materials like plastics and rubber. This helps to reduce production costs and increase productivity.

- Compatibility: EBS is compatible with a wide range of materials, making it a versatile additive for use in various manufacturing processes.

Applications of EBS in Manufacturing

Because of its beneficial properties, ethylene bis-stearamide is used in many manufacturing applications, including:

- Plastic processing: EBS is commonly used in the production of plastic products such as bags, films, and containers. It acts as a lubricant during the molding process, reducing friction between the mold and the material being molded.

- Textile industry: EBS is added to synthetic fibers and fabrics to improve their texture and wear resistance, as well as to reduce static buildup.

- Paper manufacturing: EBS is used in the production of paper to improve the release of fibers from the paper machine, reduce dust buildup, and improve the surface texture of the paper.

- Agriculture and food packaging: EBS is used in the production of agricultural films and food packaging materials due to its anti-block and anti-static properties.

- Personal care products: EBS is used in personal care products like lotions, shampoos, and soaps as a thickening agent and stabilizer.

Tips for Using EBS in Manufacturing Processes

If you're new to using EBS in your manufacturing processes, here are a few tips to help you get started:

1. Choose the right grade of EBS for your application. EBS is available in various grades depending on the intended application. Be sure to choose the grade that best suits your needs.

2. Use the recommended amount of EBS. The recommended amount of EBS to use will depend on the application and the materials being processed. Be sure to use the recommended amount to avoid overuse or underuse of the additive.

3. Mix the EBS thoroughly with the base material. To ensure that the EBS is evenly distributed, it's important to mix it thoroughly with the base material before processing.

4. Consider the processing temperature. EBS has a high melting point, so it's important to consider the processing temperature when adding it to your materials. If processed at too high or too low temperatures, the EBS may not distribute evenly or may not perform as expected.

5. Store EBS properly. Store EBS in a cool, dry place away from direct sunlight and moisture, and be sure to keep it in a sealed container to prevent contamination.


Ethylene Bis-Stearamide is a highly versatile additive used in a variety of manufacturing industries. Its lubricating, anti-block, anti-static, and processing aid properties make it a valuable tool for improving product quality, reducing costs, and increasing productivity. By considering the properties and applications of EBS, and using it properly in your manufacturing processes, you can achieve better results in your production and improve your bottom line.
