Features and Advantages of Ethylenebisstearamide (EBS)

Lubricant in Polymer Processing:

EBS serves as a highly effective lubricant for polymers such as ABS, AS, hard PVC, polyformaldehyde, polycarbonate, polyurethane, and phenol-formaldehyde resins. Its dual role as an internal and external lubricant enhances processing efficiency, particularly in demoulding applications where concentrations of 0.5-1.5% are recommended.

Anti-Adhesive Agent for Polymer Films:

In polymer films and sheets, EBS functions as an anti-adhesive agent, preventing air bubble formation and imparting slipperiness to plastic bags at concentrations of 0.5-1%, facilitating easier handling and opening.

Enhancer of Heat-Resistant and Weather-Resistant Properties:

EBS significantly improves the heat and weather resistance of polymers, especially when combined with inorganic fillers in formulations for PVC and polyolefins. Its ability to enhance dispersion and coupling properties with pigments and fillers contributes to heightened product durability and performance.

Nucleation Transparency Agent:

Used in polyolefins, polyformaldehyde, and polyamide, EBS acts as a nucleation transparency agent, reducing nucleation time, refining resin structure, and enhancing mechanical properties and transparency in final products.

Enhancer in Synthetic Fiber Industry:

EBS plays a pivotal role in enhancing heat and weather resistance in polyester and polyamide fibers. It reduces yarn breakage during antistatic nylon fiber spinning, thereby enhancing overall production efficiency and product quality.

Processing Auxiliary in Rubber Industry:

In rubber processing, EBS serves as a processing aid, improving demoulding properties and modifying filler performance. It also enhances surface smoothness in rubber products, serving as an effective polishing agent.

Coating Additive for Improved Properties:

As an additive in coatings, EBS improves pigment and filler dispersion, enhances surface leveling properties, and increases resistance to water, acids, and alkalis. Its inclusion in nitrocellulose lacquers provides a flatting effect, enhancing the aesthetic and protective qualities of coated surfaces.

Lubricant in Powder Metallurgy (PM):

EBS functions as a lubricant in powder metallurgy applications, reducing inter-particle and die-wall friction during compaction. This improves powder compressibility and facilitates easier component ejection from moulds, enhancing manufacturing efficiency.

Paper-Making Industry:

In paper-making, EBS acts as a defoamer and anti-foaming agent, improving paper quality by reducing foam formation during production. It also serves as a coating component, enhancing surface characteristics and printability.

Dope and Oil Paint Additive:

EBS enhances the salt mist and damp-proof effects in dope and oil paints, improves paint removal performance, and acts as a dulling agent for furniture polishing and printing ink applications. Its wear-resistant and smoothing properties contribute to enhanced surface finishing and air release in porous materials.

Applications of EBS

Additive in Polymers

Ethylenebisstearamide (EBS) can be seamlessly integrated into polymers to prevent undesired adhesion, particularly under high temperatures and pressures. It inhibits the sticking of adhesive granules during storage and prevents the attraction of dirt or cohesion of adhesive film layers before application. Additionally, EBS enhances the dispersion of fillers in polymer matrices, improving overall material performance.

Binder and Dispersant

Beyond plastics, EBS serves as a binder in precision engineering for metal parts. Its excellent dispersing ability and surface migration make it valuable in the formulation of printing inks, contributing to improved ink properties. This enhances the quality and durability of printed materials, making EBS a crucial component in the printing industry.

Asphalt Modifier

In the bitumen industry, EBS acts as an asphalt modifier. When incorporated into asphalt binders for road construction, it elevates the softening point and enhances visco-elasticity. This results in increased durability and performance of asphalt mixtures, ensuring longer-lasting and more resilient road surfaces.
