Description

Sodium 4-Perfluorononyloxybenzenesulphonate is a high-performance fluorinated anionic surfactant. Its unique molecular structure, featuring a perfluorinated alkyl chain, provides exceptional surface activity, thermal stability, and chemical resistance. This compound is essential for manufacturers requiring advanced wetting, leveling, and anti-foaming properties in demanding environments. Key industries that utilize this specialty chemical include advanced polymer processing, high-performance coatings, and specialized fire-fighting foams.

Application

• Fluoropolymer Processing Aid: Acts as a critical surfactant and dispersion agent in the emulsion polymerization of PTFE (Polytetrafluoroethylene) and other fluoropolymers.
• High-Performance Coatings & Films: Provides superior wetting and leveling properties in fluorinated coatings, resulting in smooth, defect-free surfaces with enhanced water and oil repellency.
• Fire-Fighting Foams (AFFF - Aqueous Film-Forming Foam): Serves as a key fluorosurfactant component to generate stable, fast-spreading aqueous films that rapidly suppress hydrocarbon fuel fires.
• Specialty Cleaning & Etching Formulations: Used in precision industrial cleaners and semiconductor etching solutions where low surface tension and chemical inertness are paramount.
• Textile & Leather Treatment: Imparts durable water, oil, and stain repellency to fabrics and leather goods.
• Paper & Packaging Coatings: Enhances grease resistance and release properties in food-contact paper and packaging materials.

Quality Control

Every batch of Sodium 4-Perfluorononyloxybenzenesulphonate is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards and specifications for fluorinated surfactants. Comprehensive testing includes identity confirmation, assay/purity determination, and control of critical impurities. A Certificate of Analysis (COA) documenting all test results is provided with each shipment to guarantee traceability and product consistency.

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); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
