Description

Poly(Oxy-1,2-Ethanediyl), .Alpha.,.Alpha.-(1-Methyl-1,2-Ethanediyl)Bis.Omega.-(9Z)-1-Oxo-9-Octadecenyloxy- is a specialized non-ionic surfactant and emulsifier derived from oleic acid and a branched polyether diol. This compound is engineered to provide excellent surface activity, stability, and compatibility in complex formulations. It is a critical raw material for industries requiring high-performance emulsification, lubrication, and dispersion, particularly where thermal and hydrolytic stability are paramount. Key sectors utilizing this chemical include advanced polymer processing, high-grade lubricant additives, and specialty coatings.

Application

• Polymer Processing Aid & Internal Lubricant: Acts as a processing aid and internal lubricant in engineering plastics (e.g., PVC, polyolefins) to improve flow, reduce torque, and prevent die buildup.
• High-Performance Lubricant & Grease Additive: Serves as a key component in synthetic lubricants and greases, enhancing film strength, reducing friction, and improving thermal stability.
• Specialty Coating & Ink Formulations: Functions as a dispersant and wetting agent in solvent-based coatings, inks, and adhesives to ensure uniform pigment dispersion and smooth application.
• Metalworking Fluid Concentrate: Used in the formulation of synthetic and semi-synthetic metalworking fluids, providing emulsification, lubrication, and corrosion inhibition.
• Fiber & Textile Processing: Employed as a spin finish additive and lubricant for synthetic fibers to reduce friction and static during high-speed processing.
• Personal Care & Cosmetic Emulsions: Utilized as a non-ionic emulsifier and emollient in high-end cosmetic products, such as creams and lotions, for stable oil-in-water emulsions.
