Tributyl phosphate is widely used as a solvent and plasticizer in industrial applications. It is commonly employed in the extraction of metal ions, especially in nuclear fuel processing, where it helps separate uranium and plutonium from spent reactor fuels through liquid-liquid extraction processes. It also serves as a flame retardant and softening agent in plastics, improving flexibility and durability. In hydraulic and lubricating systems, it acts as a component in synthetic hydraulic fluids due to its thermal stability and low volatility. Additionally, it is used in paint and coating formulations to enhance flow and reduce foaming. Its ability to stabilize emulsions makes it useful in some pesticide formulations and industrial cleaners.
