Description

N n-Dimethyl-9-Octadecenamide is a high-purity oleamide derivative, also known as oleic acid dimethylamide. This compound serves as a versatile intermediate and functional additive, valued for its surfactant properties and ability to modify surface characteristics. It is essential for manufacturers in the polymer, lubricant, and personal care industries seeking to enhance product performance and processing.

Application

• As a slip agent and anti-blocking agent in polyolefin films (e.g., LDPE, LLDPE) to improve surface properties.
• Functioning as a lubricant and processing aid in polymer compounding and extrusion to reduce viscosity and energy consumption.
• Utilized as a corrosion inhibitor and friction modifier in specialty lubricants and metalworking fluids.
• Acting as a surfactant and emulsifier in the formulation of coatings, inks, and personal care products.
• Serving as a key chemical intermediate for the synthesis of more complex amides and quaternary ammonium compounds.
• Used in research and development for studying surface interactions and self-assembly phenomena.
