TRIS(2-ETHYLHEXYL)PHOSPHATE

Tris(2-ethylhexyl) phosphate, a clear, viscous liquid, is used as a component of vinyl stabilizers, grease additives, and flame-proofing compositions; however, it is used primarily as a plasticizer for vinyl plastic and synthetic rubber compounds. Tris(2-ethylhexyl) phosphate has been employed as a speciality flame-retardant plasticizer for vinyl compositions where low-temperature flexibility is critical, eg, in military tarpaulins. It can be included in blends with general-purpose plasticizers such as phthalate esters to improve low-temperature flexibility.

Reactivity Profile
Tris(2-ethylhexyl) phosphate is incompatible with oxidizing materials. Tris(2-ethylhexyl) phosphate may soften or deteriorate certain plastics and elastomers. 

Tris (2-ethylhexyl) phosphate (TEHP) has been widely used as a plasticizer, fire retardant and solvent. As a plasticizer, it is used as a component of vinyl stabilizers, grease additives and flame-proofing compositions for vinyl plastic and synthetic rubber compounds. As a fire retardant, it is used in consumer products, such as clothing. As a solvent, it is used as a co-solvent to produce hydrogen peroxide. 

Tris (2-ethylhexyl) phosphate ( TEHP ) is an organic chemical compound from the group of phosphoric acid esters (triakyl phosphates).

Occurrence
Since tris (2-ethylhexyl) phosphate dissolves very easily from the polymers, it occurs in house dust, among other things.

USE
Due to its properties (among other things, it is slightly biocidal ), tris (2-ethylhexyl) phosphate has a wide range of uses:

-as a plasticizer with excellent low temperature flexibility and flame retardant in polymers ( PVC , PUR , NBR and others)
-as a carrier material for pigments and dyes for coloring polymers
-as a component of cutting oils
-as a component of release agent preparations used in the metal industry
-as a solvent for hydrogen peroxide synthesis

Phosphoric acid alkyl esters are used as alkylation agent for nitrogen heterocyclic compounds and as catalysts to produce phenolic and urea resins. They are used flame retarding plasticizers for cellulose esters, lacquers, plastic and vinyl resins as well as dispersing agents in plastisols. They are used as solvents in liquid-liquid extractant or separation agent of metals. They are is used as heat-exchange media, pigment grinding assistants and antifoaming agents.

Tris(2-ethylhexyl) PhosphatePerformance and application
1. Tris(2-ethylhexyl) Phosphate is colorless liquid
2. In anthraquinone method in the production of hydrogen peroxide instead of hydrogenated terpene alcohols, make the product concentration is high, the quality is good, its consumption also can be used for cold-resistant plasticizer of PVC

Tris (2-ethylhexyl) phosphate is primarily used as an additive in vinyls and synthetic rubbers to impart or enhance light stability, weather resistance and flame retardant properties. The chemical is also used as a solvent in the production of hydrogen peroxide, as a carrier in the manufacture of pigments for plastics and as an additive for mineral oils.
