Description

Erucyl Stearamide is a high-performance, long-chain fatty acid amide derived from erucic and stearic acids. This compound serves as a highly effective slip and anti-blocking agent, significantly improving the surface properties and processability of polymer films. It is essential for manufacturers in the plastics, packaging, and masterbatch industries seeking to enhance product quality and production efficiency. Its unique structure provides excellent compatibility and thermal stability in various polyolefin systems.

Application

• Primary slip and anti-blocking agent for polyethylene (PE) and polypropylene (PP) films.
• Internal lubricant for improving mold release and flow in polymer processing.
• Key additive in plastic masterbatches and compounds for consistent dispersion.
• Surface modifier to reduce coefficient of friction (COF) in packaging films and sheets.
• Used in the production of agricultural films, stretch films, and industrial liners.
• Additive for synthetic fibers and thermoplastic resins to improve finish.

Quality Control

Our Erucyl Stearamide is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing to ensure consistent purity, performance, and compliance with industry specifications. Certificates of Analysis (COA) documenting key parameters such as amide content, acid value, iodine value, and color are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance.
