Application

Tris(2-ethylhexyl) phosphate serves primarily as a plasticizer for vinyl plastics and synthetic rubber compounds, enhancing their flexibility and durability. It is a clear, viscous liquid that plays a crucial role in various applications. Notably, it is an essential component in vinyl stabilizers, grease additives, and flame-proofing compositions. Its unique properties also make it valuable as a specialty flame-retardant plasticizer, especially where low-temperature flexibility is vital, such as in military tarpaulins. Furthermore, Tris(2-ethylhexyl) phosphate can be effectively blended with general-purpose plasticizers like phthalate esters to augment low-temperature performance. Additionally, it functions as a solvent and antifoaming agent.
