Description

Distearic Acid, Diamide With n-(2-Aminoethyl)Ethane-1,2-Diamine is a high-purity, synthetic diamide compound derived from stearic acid and a polyamine. This specialized chemical serves as a highly effective slip agent, internal lubricant, and processing aid in polymer manufacturing. It is primarily required by producers of engineering plastics, films, and synthetic fibers to improve surface finish, reduce friction, and enhance processing efficiency.

Application

• Polymer Processing Aid: Acts as an internal lubricant and slip agent in polyolefins (e.g., PP, PE), polyamides (nylon), and engineering thermoplastics to improve mold release and reduce processing torque.
• Film Manufacturing: Used as an anti-blocking and slip additive in cast and blown films to prevent layers from sticking together and to improve surface smoothness.
• Synthetic Fiber Production: Functions as a spin finish component and lubricant for synthetic fibers like polyester and nylon to reduce fiber-to-fiber friction and breakage during high-speed processing.
• Masterbatch Formulation: A key ingredient in additive masterbatches and concentrates designed to impart lubricity and anti-blocking properties to the final polymer compound.
• Inks and Coatings: Employed as a flow and leveling agent, as well as a slip additive, to improve the surface properties and scratch resistance of industrial coatings and printing inks.
