EPA chemical information Information provided by: ofmpub.epa.gov (external link)
properties tricresyl phosphate is colorless to light yellow transparent oily liquid, odorless, slightly fluorescent, stable in nature, non-volatile and flame retardant.
application tricresyl phosphate is a standard flame retardant plasticizer for synthetic rubber, polyester and polyvinyl chloride, which can give polymers good wear resistance, weather resistance, mildew resistance, radiation resistance and electrical properties. it can also be used as gasoline additive, lubricating oil additive and hydraulic oil.
use used as analytical reagent, solvent and plasticizer for nitrocellulose
used as plasticizer for polyvinyl chloride and triacetate fiber (film film base) etc
used as plasticizer for epoxy resin adhesive, with flame retardant properties.
used as gas chromatography stationary liquid (the maximum service temperature is 125 ℃, the solvent is ether), separation and analysis of aromatic hydrocarbons, phenolic isomers, halides, mercaptans, etc.
