Description

Sodium 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-Heptadecafluoro-1-Octanesulfonate is a high-performance fluorinated anionic surfactant, valued for its exceptional chemical and thermal stability, low surface tension, and oil/water repellency. This compound is a critical raw material for demanding applications where standard hydrocarbon-based surfactants fail. It is primarily sought by manufacturers in the specialty polymer, electronics, and advanced materials sectors for its unique perfluorinated chain properties.

Application

• Fluoropolymer Production: Acts as an emulsifier and processing aid in the synthesis of PTFE (Teflon™), FEP, and PFA, improving dispersion and final product quality.
• Fire-Fighting Foams (AFFF): A key ingredient in aqueous film-forming foams (AFFF) for rapidly suppressing hydrocarbon fuel fires.
• Electroplating & Metal Finishing: Used as a wetting agent and mist suppressant in chromium plating and other hard metal plating baths to improve surface quality and reduce environmental emissions.
• Coating & Surface Treatment: Imparts superior oil, water, and stain repellency to textiles, leather, paper, and carpets as a durable water repellent (DWR) finish.
• Electronic Chemicals: Employed as a surfactant in photoresist developers and etching solutions for semiconductor manufacturing to ensure uniform wetting and cleaning.
• Specialty Detergents & Cleaners: Formulated into industrial and institutional cleaners for challenging surfaces where low surface tension and high stability are required.

Quality Control

Our Sodium 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-Heptadecafluoro-1-Octanesulfonate is manufactured under a strict quality management system. Each batch is analyzed to ensure it meets precise specifications for purity and performance, with particular attention to the control of related substances. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is provided with every shipment to guarantee traceability and compliance for your regulatory needs.

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 quality and handling properties.
