Tributyl phosphate (TBP) is a strong polar solvent used in the production of solutions of synthetic resins and natural rubber. In both cellulose based plastics and synthetic resins, TBP is used as a flame-retarding plasticizer.
- TBP is employed as a pasting agent for pigment pastes.
- Due to the limited influence of temperature on the viscosity of TBP, it also serves as an important component in the manufacture of hydraulic fluids for aircraft.
- As a very strong wetting agent, TBP is used in the textile industry and in the field of adhesives. As a neutral extractant it is able to extract both acids and metal cations.
