Description

Distearyl Phthalic Acid Amide CAS NO 87787-81-3 is a high-molecular-weight organic amide derived from phthalic acid and stearyl amine. This compound is valued for its excellent performance as a lubricant, slip agent, and anti-blocking additive in polymer processing. It is primarily needed by manufacturers in the plastics, coatings, and specialty chemical industries seeking to improve surface properties and processing efficiency of their materials.

Application

As a highly effective internal and external lubricant for polyolefins (PP, PE) and engineering plastics.
As a slip and anti-blocking agent in plastic films and sheets to prevent adhesion.
As a processing aid to reduce melt viscosity and improve flow in polymer extrusion and molding.
As a surface modifier in masterbatches and pigment concentrates for better dispersion.
As an additive in coatings and inks to enhance surface smoothness and scratch resistance.
As a component in synthetic wax blends and release agents for various industrial applications.
