Description

N,N'-Dioctadecyladipamide is a high-purity, synthetic diamide compound with a long-chain aliphatic structure. This specialty chemical serves as a highly effective slip agent, internal lubricant, and nucleating agent, significantly enhancing the processing and performance characteristics of various polymer systems. It is essential for manufacturers in the plastics, coatings, and specialty chemical industries seeking to improve product surface quality, reduce friction, and optimize crystallization behavior.

Application

• Primary slip and anti-blocking agent in polyolefin films (e.g., LDPE, LLDPE, HDPE) for packaging.
• Internal lubricant and process aid to reduce torque and improve flow in engineering plastics and masterbatches.
• Nucleating agent to promote uniform crystallization, increase clarity, and enhance mechanical properties in semi-crystalline polymers like polypropylene.
• Surface modifier to improve gloss and scratch resistance in coatings and paints.
• Additive for synthetic fibers to reduce fiber-to-fiber and fiber-to-metal friction during processing.
• Component in hot-melt adhesives and sealants to modify rheological properties and surface release.
• Raw material for the synthesis of other specialty surfactants and lubricant additives.

Quality Control

Our N,N'-Dioctadecyladipamide is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity and performance. A comprehensive Certificate of Analysis (COA) detailing assay, melting point, color, and acid/amine values is provided with each shipment to guarantee compliance with your specifications and industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect performance. Keep away from strong oxidizing agents.
