Description

Stearanilide is a high-purity organic amide compound, serving as a versatile intermediate and functional additive in advanced chemical synthesis. Its value lies in its ability to act as a slip agent, lubricant, and coupling agent, enhancing the performance and processing characteristics of various industrial formulations. This product is essential for manufacturers in the plastics, rubber, personal care, and specialty chemical industries seeking to improve product quality and production efficiency.

Application

• As a slip and anti-blocking agent in polyolefin films (e.g., LDPE, LLDPE) to reduce surface friction and prevent adhesion.
• As an internal lubricant and processing aid in PVC, engineering plastics, and synthetic rubber compounds to improve flow and mold release.
• As a key intermediate in the synthesis of surfactants, corrosion inhibitors, and other specialty chemicals.
• As a viscosity modifier and stabilizer in greases, waxes, and cosmetic formulations (e.g., lipsticks, creams).
• As a water repellent and fiber treatment agent in textiles and paper coatings.
• As a compatibilizer and dispersing agent in pigment masterbatches and filler-loaded polymer systems.
