Flame retardancy efficacy of phytic acid: An overview

Abstract

The article reviews the different methods of which, phytic acid (PA) can be employed as a flame retardant (FR) filler for different polymeric materials. The methods are critically discussed, based on the available literature and patents. Depending on the method used and the addition of FRs into a PA flame retarded system, different flame retarding modes of action and fire resistance performances are attained. The mechanism of action for PA-based system remains similar to those observed in other phosphorus-based FRs, namely, condensed and gas-phase mechanisms.
