Description

Octadecanamide, N-Methyl- is a high-purity fatty acid amide derivative, also known as N-Methylstearamide. This compound serves as a crucial intermediate and functional additive in advanced material synthesis and industrial formulations. It is primarily sought after by manufacturers in the polymer, lubricant, and personal care industries for its role as a slip agent, internal lubricant, and processing aid. Our supply ensures consistent quality and reliable global availability for your production needs.

Application

• As a highly effective slip and anti-blocking agent in polyolefin films (e.g., LDPE, LLDPE, HDPE).
• Functioning as an internal lubricant and mold release agent in engineering plastics and rubber compounds to improve processing.
• Utilized as a key intermediate in the synthesis of quaternary ammonium compounds and other specialty surfactants.
• Acting as a viscosity modifier and texture enhancer in cosmetic and personal care formulations, such as creams and sticks.
• Employed as a waterproofing agent and fiber treatment in textile and paper coating applications.
• Serving as a corrosion inhibitor component and additive in industrial lubricants and metalworking fluids.
