Description

Ethylenenpalmitamidenstearamide is a high-performance bisamide wax, specifically an ethylene bis-stearamide/palmitamide blend, widely recognized for its excellent lubricating and anti-blocking properties. This compound is critical for enhancing processability and surface finish in polymer formulations, reducing friction and preventing adhesion during manufacturing. It is an essential additive for industries requiring superior mold release, including plastics, rubber, and coatings.

Application

• Primary internal and external lubricant for PVC, polyolefins (PP, PE), and engineering plastics to improve flow and reduce torque.
• Anti-blocking and slip agent in polymer films and sheets to prevent adhesion during storage and processing.
• Mold release agent in rubber compounding and injection molding applications for easier part ejection.
• Viscosity modifier and processing aid in masterbatches and color concentrates for uniform dispersion.
• Surface finishing agent in paints, inks, and coatings to enhance gloss and scratch resistance.
• Additive in adhesives and sealants to control tack and improve application properties.
• Textile fiber lubricant to reduce friction during high-speed spinning and weaving operations.
• Component in cosmetic formulations such as lipsticks and creams for its texture-enhancing and stabilizing effects.
