1. Basic Information

•  Name: Sodium Perfluorononyloxybenzenesulfonate

• Common Abbreviation: OBS

• CAS Number: 87-56-8

• Molecular Formula: C₁₅H₅F₁₉O₄S·Na

• Appearance & Properties: White powder; solid at room temperature.

Purity: 98%

• Type: Anionic fluorosurfactant.

• Solubility: Soluble in water; often co-dissolved with alcohols in some formulations to improve dispersibility.

• Stability: High thermal and chemical stability; resistant to acids, alkalis, salts, and oxidizing agents.

2. Product Applications

• Fire Fighting: Used in high-efficiency fluoroprotein foam fire extinguishing agents to significantly improve spreading ability and liquid resistance, suitable for fires involving polar flammable liquids such as alcohols and ketones.

• Oil & Gas Exploration: Serves as a cleanup additive in secondary/tertiary oil recovery and fracturing fluids, reducing oil-water interfacial tension to enhance plug removal and flowback efficiency.

• Precision & Metal/Steel Plate Cleaning: Improves wetting and decontamination performance, minimizing residue and corrosion risks.

• Coatings & Inks: Enhances leveling, spreading, and pigment wetting, reducing surface tension to prevent cratering and roll sticking.

• Paper Making & Coating: Stabilizes paraffin-rosin-water dispersion systems, improving sizing and water resistance.

• Others: Applied in latex emulsification, electronic antistatic treatment, stabilization of PTFE/fluoropolymer dispersions, and chromium mist suppression in electroplating.

3. Key Usage & Compatibility Notes

• Dosage: Typically 0.01%–0.1% (w/w), optimized based on the system and target surface/interfacial tension.

• Compatibility: Compound with hydrocarbon surfactants for synergistic efficiency and cost reduction.

• Preparation: Ensure full dissolution before use to avoid uneven dispersion affecting performance.
