Diammonium Phosphate (Flame Retardant Grade)
Diammonium phosphate (DAP) flame retardant grade is an inorganic phosphorus-nitrogen salt widely used in fire-retardant treatments for wood, paper, and agricultural biomass. Its higher nitrogen content and alkaline decomposition characteristics complement monobasic ammonium phosphate in blended fire-retardant formulations. DAP releases ammonia and phosphoric acid upon heating, forming a phosphate ester char layer that retards pyrolysis and reduces flame spread.
