Description

Octadecanamide CAS NO 124-26-5 is a high-purity, long-chain fatty acid amide widely recognized for its excellent lubricating and release properties. This versatile compound serves as a crucial intermediate and functional additive across multiple high-value manufacturing sectors. It is particularly essential for industries requiring reliable slip agents, mold release agents, and anti-blocking agents, such as polymer processing, coatings, and personal care formulations.

Application

• Polymer & Plastics Processing: Acts as an effective internal and external lubricant and slip agent for polyolefins (e.g., PE, PP), PVC, and engineering plastics, improving processing flow and reducing friction.
• Mold Release Agent: Used in rubber and plastic molding operations to prevent sticking and ensure clean, consistent part release from molds.
• Anti-blocking Agent: Incorporated into polymer films and sheets to prevent adhesion between layers during storage and transport.
• Personal Care & Cosmetics: Functions as a viscosity modifier, opacifier, and conditioning agent in creams, lotions, and hair care products.
• Coatings & Inks: Imparts slip and mar resistance to surface coatings, paints, and printing inks, enhancing surface feel and durability.
• Textile & Fiber Industry: Serves as a softening agent and spin finish component for synthetic fibers, improving yarn processability and hand feel.
• Chemical Intermediate: A key starting material for the synthesis of other specialty amides, surfactants, and corrosion inhibitors.
