What is Ethylene-Bis-Stearamide EBS?
Ethylene Bis Stearamide, or EBS for short, is a high melting point synthetic wax with the chemical formula C30H58N2O2 and CAS No. 110-30-5. It has demonstrated a wide range of applications as a multifunctional additive in a number of industrial fields. The molecular structure of EBS contains two amide groups (-C -NH-), which endows it with unique performance characteristics.
Properties of Ethylene-Bis-Stearamide:
– High melting point and virtually insoluble in common solvents at room temperature.
– It has good internal and external lubricating properties, which improves the efficiency of plastic processing and the quality of products.
– Improve the surface finish and smoothness of products.
– Provide antistatic effect, reduce the product’s adsorption of dust.
– When used in conjunction with other lubricants, it has a synergistic effect that further enhances performance.
Due to its unique combination of properties, EBS is a very important functional additive in the plastics and related industries.
Ethylene Bis Stearamide uses include:
- Plastics processing aids:EBS is used as an internal and external lubricant in the plastics industry. As an internal lubricant, it improves the melt flowability of the resin, which helps to reduce internal friction and make the plastic melt flow more easily, thus improving the physical properties and appearance quality of the products. As an external lubricant, it reduces the friction between the plastic and the surface of processing equipment, improves mold release, reduces energy consumption, and gives products excellent surface finish and smoothness. It is widely used in the molding process of PVC, ABS, high-impact polystyrene, polyolefin, and other plastics.
- Antistatic agent:The molecular structure of EBS allows it to impart certain antistatic properties products after it is added to tactics and reduce the phenomenon of “dust absorption,” which is especially important for home appliances, instrument housings, and engineering plastics.
- pigment dispersant:it can help to improve the dispersibility of colorants and fillers in plastics, making the operation process smoother and the final product quality improved.
- Rubber industry:It can also be used as a lubricant in rubber products to improve processing performance and product quality.
- Coatings and inks:As an additive, EBS can improve the flow and surface smoothness of coatings and inks to enhance their application performance.
- Other applications:EBS can also be used as resin additives, paraffin wax gloss agents, etc., as well as playing a role in the chemical fiber industry in the antistatic treatment and heat and weather resistance enhancement.
What is EBS emulsion water-based Ethylene Bis Stearamide?
EBS emulsions （water-based Ethylene Bis Stearamide） are generally referred to as products that contain Ethylene Bis Stearamide in emulsion form. Ethylene Bis Stearamide (EBS) itself is an excellent additive mainly used in the plastics, rubber, and coatings industries as a lubricant, dispersant, and anti-adhesion agent.
Characteristics of EBS emulsion:
Dispersibility and stability: The EBS emulsion should have good water dispersibility and be evenly dispersed in water to form a stable emulsion.
Reduced friction and improved flow: Like its powder form, EBS emulsion can provide internal lubricity, reduce friction during the processing of plastics or coatings, and improve the flow performance of materials.
Surface performance improvement: It can increase the surface smoothness and gloss of products and improve the quality of film formation.
Compatibility: Compatible with a wide range of resin systems, including but not limited to PVC, PE, PP, ABS, and other plastics, as well as certain rubber and coating systems.
Environmental friendliness: EBS emulsions for water-based systems may have more environmental advantages over solvent-based products.
Applications for EBS emulsions:
Coating and ink industry: as dispersants and leveling agents to improve coating performance and surface effect of coatings.
Plastics processing: as internal and external lubricants in plastics processing to improve processing efficiency and reduce equipment wear.
Rubber products: increase the surface gloss of rubber products and improve processing performance.
Chemical fiber industry: enhances the heat resistance, weather resistance, and antistatic properties of fibers.
Water-based adhesives and sealants: Enhance the bonding strength and construction performance of products.
