Tributyl phosphate

Technical Datasheet | Supplied by Lanxess
Tributyl phosphate. Is a very strong, polar solvent. Acts as a flame-retardant plasticizer for cellulose based plastics and synthetic resins. 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. Used in the production of solutions of synthetic resins and natural rubber. Also used as a neutral extractant, it is able to extract both acids and metal cations.

Hansen Solubility Parameters

[16.1, 5.2, 7.2]
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with Tributyl phosphate. A practical determination of these HSP values would provide higher certainty. Learn More.
