Description

N,N'-Hexane-1,6-Diyldistearamide is a high-purity bisamide wax derived from stearic acid and hexamethylenediamine. This compound serves as a highly effective internal and external lubricant, processing aid, and nucleating agent in polymer formulations. It is essential for manufacturers in the plastics, coatings, and masterbatch industries seeking to improve product surface quality, enhance mold release, and optimize production efficiency.

Application

• Polymer Processing Aid & Lubricant: Acts as an internal and external lubricant in polyolefins (PP, PE), PVC, and engineering plastics to reduce melt viscosity, improve flow, and prevent sticking to processing equipment.
• Nucleating Agent: Enhances the crystallization rate and uniformity in semi-crystalline polymers like polypropylene, leading to improved clarity, stiffness, and shorter cycle times in injection molding.
• Anti-blocking & Slip Agent: Migrates to the surface of polymer films and sheets to reduce coefficient of friction (COF), preventing adhesion between layers and improving handling.
• Pigment & Filler Dispersion: Improves the wetting and dispersion of pigments and inorganic fillers in masterbatches and compounds, resulting in better color strength and mechanical properties.
• Surface Modifier: Imparts a smooth, glossy finish to molded plastic parts and extruded profiles, enhancing aesthetic quality.
• Hot Melt Adhesives & Coatings: Used as a rheology modifier and matting agent to control viscosity, set time, and surface texture.
