Description

Acetamide, n-Octadecyl- is a high-purity, long-chain fatty acid amide derivative, also known as Stearamide. This compound serves as a versatile intermediate and functional additive, valued for its excellent lubricating, anti-blocking, and slip properties. It is essential for manufacturers in the plastics, polymer, and coatings industries seeking to enhance product performance and processing efficiency.

Application

• Primary use as an internal and external lubricant and slip agent in polyolefin films (e.g., LDPE, LLDPE, HDPE) and other polymers.
• Acts as an effective anti-blocking agent to prevent film layers from sticking together during production and storage.
• Employed as a processing aid and mold release agent in the injection molding and extrusion of engineering plastics.
• Functions as a viscosity modifier and dispersant in inks, coatings, and cosmetic formulations.
• Used in the synthesis of other specialty chemicals, including surfactants and corrosion inhibitors.
• Applied as a fiber finishing agent in the textile industry to improve yarn processing and hand feel.
