Description

Ammonium 1,1,2,2,3,3,4,4,5,5,6,6,7,7,7-Pentadecafluoroheptane-1-Sulphonate is a high-performance fluorinated surfactant and electrolyte salt, valued for its exceptional chemical and thermal stability derived from its perfluorinated carbon chain. This compound is a critical material for applications requiring superior surface activity, hydrophobicity, and oleophobicity in demanding environments. It is primarily sought by manufacturers in the electronics, specialty polymer, and advanced materials sectors for its unique combination of properties.

Application

• Firefighting Foams (AFFF): A key ingredient in aqueous film-forming foams for suppressing hydrocarbon fuel fires.
• Electroplating & Surface Treatment: Used as a wetting agent and mist suppressant in chromium plating and other metal finishing baths.
• Specialty Polymer Synthesis: Acts as an emulsifier in the polymerization of fluorinated monomers (e.g., PTFE, FKM) and as a functional additive to impart oil and water repellency.
• Lithium-Ion Battery Electrolytes: Employed as a conductive salt or additive to enhance electrolyte stability and battery performance at high voltages.
• Coating & Ink Formulations: Provides leveling, anti-cratering, and substrate wetting properties in high-performance fluoropolymer coatings and inks.
• Etching & Cleaning Solutions: Serves as a surfactant in acidic or alkaline formulations for semiconductor wafer cleaning and etching processes.
