Chemical Properties:
Trioctyl 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.
Trioctyl Phosphate has been employed as a specialty flameretardant plasticizer for vinyl compositions where low temperature flexibility is critical, eg, in military tarpaulins.
Trioctyl Phosphate can be included in blends with general purpose plasticizers such as phthalate esters to improve low temperature flexibility.
Uses:
Trioctyl Phosphate is used as a phosphorous flame retardant.
Used as a plasticizer in the preparation of a new potentiometric membrane sensor.
Solvent, antifoaming agent, plasticizer.
General Description
Clear colorless to pale yellow liquid with a slight sharp odor. Insoluble in water; Soluble in alcohol, acetone, and ether. Combustible.
Trioctyl phosphate is widely used as a flame retardant, plasticizer, and extractant in the production of chemical enterprises.
Its most important use is the production of hydrogen peroxide.
As the solvent of hydrogen anthraquinone, trioctyl phosphate has the conditions of high solubility of hydrogen anthrone, high distribution coefficient of hydrogen peroxide between water and solvent, high boiling point and high ignition point.
TRIOCTYL PHOSPHATE - Use
can replace hydrogenated terpene pine alcohol in hydrogen peroxide produced by anthraquinone method, so that the product has high concentration, good quality and low self-consumption, and can also be used as a cold-resistant plasticizer for PVC
extractant. Plasticizer.
Trioctyl Phosphate (TEHP) is a non-flammable,colourless liquid with low water solubility and very low vapour pressure, which is used as a flame retardant and plasticizer for PVC and cellulose acetate and as a solvent.
Trioctyl Phosphate is produced from phosphorus oxychloride and 2-ethylhexanol
Trioctyl Phosphate is a plasticizer for PVC, imparting good low-temperature flexibility, resistance to water extraction, flame and fungus resistance, and minimum change in flexibility over a wide temperature range.
Trioctyl Phosphate is also compatible with polyvinyl butyral, ethyl cellulose, and cellulose acetate–butyrate resins with a high butyral content.

Overview:
Trioctyl Phosphate is a viscous, clear to pale yellow liquid at ambient temperatures.
The chemical has a slight, pungent odor.
Uses:
Trioctyl Phosphate is primarily used as an additive in vinyls and synthetic rubbers to impart or enhance light stability, weather resistance and flame retardant properties.
Trioctyl Phosphate 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.
Trioctyl phosphate is a kind of practical good fire-retardant, and one of cold resistant plasticizer is used for Vinylite, celluosic resin, resol, urethane, synthetic rubber, solvent, defoamer etc.;
Its low-temperature performance is better than the adipic acid ester class, and has mildew-resistant and fire retardation, though thermostability and plasticizing capacity are slightly poor, can with phosphoric acid triphen first and usefulness, just can improve;
With DOP and with obtaining the self-extinguishing goods, also can be used for polyvinyl chloride cable material, coating etc.
