Tributyl phosphate

Tributyl phosphate (TBP, CAS 126-73-8 ) is a phosphoric acid ester used industrially as a solvent, plasticizer, and flame retardant across a broad range of manufacturing sectors. Its ability to dissolve both polar and non-polar compounds makes it a practical choice for extraction, formulation, and process chemistry applications in various industrial environments. In nuclear fuel reprocessing and rare earth metal extraction, TBP functions as a selective solvent for separating metal ions from aqueous streams, a well-established role in hydrometallurgical processing. Printing ink and surface coating formulators use it as a solvent and defoamer, where it reduces surface tension in high-speed application processes to ensure a smooth finish. In plastics and polymer manufacturing, TBP acts as a plasticizer and flame-retardant additive, incorporated into cellulose acetate, PVC, and polyurethane systems to improve flexibility. Lubricant and metalworking fluid producers also use TBP as an anti-wear additive and carrier solvent for active ingredients in cutting and hydraulic fluid formulations for heavy machinery. Tributyl phosphate is supplied as a clear liquid in drum and IBC quantities, with bulk tanker options available for large-volume industrial buyers requiring consistent supply chains. Standard commercial grades include technical grade and high-purity solvent grade. Specifications vary by end-use, with purity levels typically ranging from 98% to 99%+ for process-sensitive applications. Contact us for supply of Tributyl phosphate Request Quote
