Description

Sodium Perfluoroheptanoate is a high-performance fluorinated surfactant and anionic perfluorinated carboxylate salt. This compound is valued for its exceptional surface activity, chemical and thermal stability, and oleophobic/hydrophobic properties derived from its perfluorinated carbon chain. It is a critical raw material for industries requiring advanced surface modification, emulsification, and water/oil repellency. Key sectors utilizing this specialty chemical include advanced polymer manufacturing, fire-fighting foams, and high-performance coatings.

Application

• Fluoropolymer Manufacturing: Acts as an emulsifier and processing aid in the polymerization of PTFE (Teflon®), FEP, and PFA.
• Fire-Fighting Foams (AFFF): A key component in aqueous film-forming foams (AFFF) for rapidly suppressing hydrocarbon fuel fires.
• Specialty Coatings & Textiles: Imparts durable water, oil, and stain repellency to fabrics, carpets, and paper products.
• Electronics & Semiconductor: Used in etching baths and as a surfactant in the production of electronic components.
• Industrial Cleaners & Degreasers: Enhances the wetting and penetrating power of formulations for critical cleaning applications.
• Pharmaceutical & Agrochemical Intermediates: Serves as a building block for synthesizing more complex fluorinated molecules.

Quality Control

Our Sodium Perfluoroheptanoate is manufactured under strict quality management systems. Each batch is analyzed to ensure it meets precise chemical and physical specifications, including purity, ionic content, and absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing assay, identity, and impurity profiles is provided with every shipment. We adhere to relevant industry standards and can support compliance documentation for global regulatory frameworks.

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); containers must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from strong acids and strong alkalis.
