Description

Sodium 1H,1H,2H,2H-Perfluorooctanesulfonate is a high-performance fluorinated anionic surfactant and a key per- and polyfluoroalkyl substance (PFAS) derivative. This compound is valued for its exceptional ability to dramatically lower surface tension and provide superior oil, water, and stain repellency. It is a critical raw material for manufacturers in the textile finishing, fire-fighting foam (AFFF), and specialty coatings industries, where durable surface modification is required.

Application

• Fire-Fighting Foams (AFFF): A critical component in aqueous film-forming foams (AFFF) used for suppressing flammable liquid fires, particularly in aviation, petrochemical, and military applications.
• Textile & Carpet Treatment: Imparts durable water, oil, and stain repellency to fabrics, carpets, and upholstery for performance and protective apparel.
• Specialty Coatings & Surface Modifiers: Used in formulations for paper coatings, leather treatments, and industrial coatings to provide release and barrier properties.
• Electroplating & Metal Plating: Acts as a wetting agent and mist suppressant in chromium plating baths and other electroplating processes to improve surface quality and reduce environmental emissions.
• Polymerization Aid: Serves as an emulsifier or surfactant in the emulsion polymerization of fluorinated monomers.
• Electronic & Semiconductor Industry: Used in photoresist formulations and as a surfactant in etching and cleaning solutions for wafer processing.

Quality Control

Our Sodium 1H,1H,2H,2H-Perfluorooctanesulfonate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for assay and purity, to ensure it meets precise customer specifications and relevant industry standards. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance and handling.
