1. Performance and use:

Triphenyl phosphate (TPP) is a colorless crystalline powder with a faint, phenol-like odor.

Triphenyl phosphate is known as a product with manifold fields of applications regarding its qualities in particular as a flame retardant.   One primary use is as a flame retardant in phenolic- and phenylene oxide-based resins for the manufacture of electrical and automobile components, for auto upholstery, and as a nonflammable plasticizer in cellulose acetate for photographic films.

Triphenyl phosphate (TPP) has also been used to impregnate roofing paper.

Triphenyl phosphate occurs as a plasticizer in various lacquers and varnishes (O'Neil, 2006), and as a component of lubricating oil and hydraulic fluids (ACGIH, 2012).

Triphenyl Phosphate is used in the insecticidal composition.

Triphenyl Phosphate is also use in hydraulic liquids, and adhesives, inks, coatings, as a plasticizer in lacquers and varnishes, and as a substitute for camphor in celluloid materials to make the latter stable and fireproof.
