Description

n-Oleylstearamide is a high-purity, long-chain fatty acid amide derived from oleic and stearic acids. This compound serves as a highly effective slip agent, internal lubricant, and anti-blocking additive, significantly improving the surface properties and processing characteristics of various polymer systems. It is essential for manufacturers in the plastics, coatings, and synthetic fiber industries seeking to enhance product quality and production efficiency.

Application

• Primary slip and anti-blocking agent for polyolefin films (LDPE, LLDPE, HDPE, PP).
• Internal lubricant and mold release agent for engineering plastics and thermoplastic processing.
• Surface modifier to improve texture and gloss in paints, inks, and coating formulations.
• Additive for synthetic fibers to reduce friction and static buildup during spinning and weaving.
• Processing aid in PVC and rubber compounds to facilitate extrusion and calendering.
• Key ingredient in the formulation of industrial waxes and polishes.
• Component in hot-melt adhesives to regulate viscosity and improve open time.
• Additive for cosmetic and personal care products, such as creams and sticks, to provide emolliency.
