Description

Sodium fluoride (CAS 7681-49-4 ), also sold under the name Floridine, is an inorganic salt sourced for its biocidal, flux, and fluoridating properties across industrial and pharmaceutical supply chains. NaF functions as a preservative, pH buffer, and fluoride source in applications ranging from water treatment to pharmaceutical manufacturing. In water treatment, NaF is dosed as a fluoridation agent. This chemical is used to adjust fluoride levels in municipal drinking water systems. Pharmaceutical and oral care formulators use it as the active fluoride source in toothpaste, mouth rinse, and topical dental preparations. In the textile, leather, and paper industries, it acts as a preservative and biocide to prevent microbial degradation during processing and storage. This ensures long-term stability for various raw materials. Building and construction applications include its use as a flame retardant additive and wood preservative treatment against fungi and insects. It provides essential protection for structural components. Sodium fluoride is available as a white crystalline powder or fine granules. Standard supply grades include USP , BP , and Ph. Eur. for pharmaceutical applications, alongside technical grade for industrial use. Purity levels typically range from 97% technical grade up to 99%+ for pharmaceutical-grade material. These high standards ensure the product meets the rigorous demands of global chemical manufacturing. Contact us for supply of Sodium fluoride Request Quote
