Description

N,N'-[Carbonylbis[(Ethylimino)Ethane-1,2-Diyl]]Distearamide is a specialized bis-stearamide derivative, functioning as a high-performance internal and external lubricant and release agent. Its molecular structure provides excellent thermal stability and compatibility with a wide range of polymer matrices, making it a critical additive for enhancing processability and final product quality. This compound is essential for manufacturers in the plastics, rubber, and coatings industries seeking to improve flow properties, reduce mold sticking, and achieve superior surface finish.

Application

• Primary internal and external lubricant for engineering plastics such as PVC, ABS, polycarbonate, and nylon.
• Mold release agent for polyurethane (PU) foams and elastomers, preventing adhesion and facilitating demolding.
• Processing aid in rubber compounding to reduce viscosity, improve filler dispersion, and lower energy consumption.
• Surface modifier and anti-blocking agent in polymer films and sheets.
• Additive in synthetic fiber production to reduce friction during spinning and drawing processes.
• Component in hot-melt adhesives and sealants to control viscosity and improve wetting properties.
• Lubricant for masterbatch and color concentrate formulations to enhance pigment dispersion.
