Description

Benzenesulfonic Acid, 4-[(Undecafluorohexenyl)Oxy]-, Sodium Salt is a specialized fluorinated surfactant and anionic electrolyte, distinguished by its unique perfluoroalkyl ether chain attached to a benzenesulfonate core. This compound is engineered to deliver exceptional surface activity, chemical resistance, and thermal stability in demanding environments where conventional surfactants fail. It is a critical raw material for advanced material science, serving industries that require high-performance wetting, leveling, and anti-foaming properties.

Application

• Fluoropolymer Processing Aid: Acts as a critical surfactant and emulsifier in the polymerization of PTFE (Teflon™), FEP, and PFA, improving dispersion and process stability.
• Fire-Fighting Foam (AFFF) Formulations: Used as a key fluorosurfactant component in aqueous film-forming foams for rapid flame suppression of hydrocarbon fuel fires.
• Specialty Coatings and Inks: Provides superior wetting and leveling in high-performance fluoropolymer coatings, printing inks, and anti-graffiti coatings.
• Electronic Chemicals: Employed as a surfactant in photoresist developers and etching solutions for semiconductor manufacturing.
• Oil & Gas Field Chemicals: Functions as a high-temperature stable surfactant in acidizing and fracturing fluids.
• Textile and Leather Treatment: Imparts oil, water, and stain repellency to fabrics and leather goods.
