TBP is an indispensable chemical used as an effective plasticizer in nitrocellulose and cellulose acetate, enhancing flexibility and durability. It is widely employed as a robust solvent and extractant for metal ions in nuclear fuel reprocessing and rare earth separation. Furthermore, TBP functions critically in high-performance hydraulic fluids, specialized coatings, and as an anti-foaming agent in concrete mixtures, making it vital for chemical processing, aviation, and advanced manufacturing.
