Description

Distearyl Phthalic Acid Amide is a high-performance synthetic organic compound belonging to the class of N,N'-disubstituted phthalamides. This specialty chemical serves as a highly effective internal/external lubricant and processing aid, significantly improving flow properties and surface finish in polymer systems. It is primarily utilized by manufacturers in the plastics, coatings, and rubber industries seeking to enhance production efficiency and final product quality.

Application

• Primary lubricant and mold release agent for engineering plastics (e.g., PVC, ABS, polycarbonate).
• Processing aid to reduce torque and improve dispersion in masterbatch and compound production.
• Surface modifier to enhance gloss and smoothness in plastic films and injection-molded parts.
• Anti-blocking and slip agent in polyolefin films and packaging materials.
• Additive in synthetic fibers to improve spin finish and fiber processing.
• Internal lubricant for rigid PVC pipes and profiles to improve extrusion rates.
• Component in coatings and inks to modify rheology and surface properties.
• Additive in rubber compounds to aid processing and improve mold flow.
