Trisodium phosphate dodecahydrate

Trisodium phosphate dodecahydrate (CAS 10101-89-0 ), commonly known as TSP, is the hydrated crystalline form of trisodium phosphate used across industrial and institutional markets. It functions as a heavy-duty cleaner, pH buffer, and sequestrant. This chemical acts as a flame retardant across a broad range of manufacturing and processing applications. In industrial cleaning and surface preparation, TSP cuts through grease, oils, and mineral deposits on metal and concrete. It is frequently applied to painted surfaces prior to coating or refinishing to ensure proper adhesion. Water treatment facilities use it to adjust pH and sequester calcium and magnesium ions, preventing scale formation. This sequestration is vital for maintaining distribution systems and boilers in high-pressure environments. Textile and paper processing operations rely on TSP to control bath pH and chelate interfering metal ions. These properties are essential during bleaching and dyeing stages to ensure color consistency. In flame retardant formulations and building materials, it contributes phosphate-based fire resistance to coatings and adhesives. The product is also utilized in construction products to enhance safety and durability. Trisodium phosphate dodecahydrate is supplied as white crystalline granules or powder for easy handling and dissolution. Standard commercial grades include technical grade and food-grade specifications meeting FCC requirements. Industrial supply is typically available in bulk bags or multi-wall sacks for large-scale operations. Food-grade material is packaged specifically to meet handling and contamination control requirements. This ensures the material remains stable and effective throughout the supply chain and final application. Contact us for supply of Trisodium phosphate dodecahydrate Request Quote
