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. 

It 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).
