Triethyl phosphate has been used commercially as an additive for polyester laminates and in cellulosics. In polyester resins it functions as a viscosity depressant and as a flame retardant. The viscosity-depressant effect of triethyl phosphate in polyester resin permits high loadings of alumina trihydrate,a fire-retardant smoke-suppressant filler. Triethyl phosphate has also been employed as a flame-resistant plasticizer in cellulose acetate.Because of its water solubility the use of triethyl phosphate is limited to situations where weathering resistance is unimportant.The halogenated alkyl phosphates are generally used for applications where lower volatility and greater resistance to leaching are required.
