Description

Poly(Oxy-1,2-Ethanediyl), α-[2-[[(Heptadecafluorooctyl) Sulfonyl]Propylamino]Ethyl]-ω-Hydroxy - CAS NO 52550-45-5 is a specialized fluorinated surfactant and polymeric material characterized by a perfluorooctylsulfonamide segment linked to a polyoxyethylene chain. This unique molecular structure imparts exceptional surface activity, thermal stability, and chemical resistance, making it a critical performance additive. It is primarily used to modify surface properties, enhance wetting, and reduce interfacial tension in demanding industrial formulations. Key industries that rely on this advanced material include high-performance coatings, fluoropolymer processing, and specialty chemical manufacturing.

Application

• Fluoropolymer Additive: Acts as a processing aid and surfactant in the manufacture of PTFE, FEP, and PFA, improving dispersion and reducing melt viscosity.
• High-Performance Coatings: Used as a leveling and wetting agent in fluorinated coatings to achieve superior water/oil repellency, chemical resistance, and a smooth finish.
• Fire-Fighting Foams (AFFF): Serves as a key fluorosurfactant component in aqueous film-forming foams for rapid flame suppression on hydrocarbon fires.
• Textile and Leather Treatment: Imparts durable water, oil, and stain repellency to fabrics, carpets, and leather goods.
• Specialty Cleaning & Etching Formulations: Enhances the wetting and penetrating power of aggressive cleaning solutions and semiconductor etching baths.
• Paper and Packaging Coatings: Provides grease resistance and barrier properties to food packaging and specialty papers.

Quality Control

Our production of this fluorinated surfactant adheres to strict quality management systems. Each batch is characterized and tested to ensure consistent performance in surface tension reduction and compatibility. Key parameters monitored include fluorine content, ethylene oxide unit distribution, residual monomers, and critical micelle concentration (CMC). Certificates of Analysis (COA) detailing assay, identity, and purity are available upon request, supporting compliance with relevant industry and supply chain requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture which may affect performance.
