Melamine Pyrophosphate
Featured inFlame Retardants
Melamine pyrophosphate is a nitrogen–phosphorus synergistic flame retardant combining the char-promoting action of phosphate with the gas-diluting effect of melamine decomposition. It exhibits superior thermal stability compared to melamine orthophosphate and is suitable for mid-to-high temperature polymer processing. The compound is widely used in intumescent coatings and polyolefin systems, providing effective fire protection through both condensed-phase char and gas-phase suppression mechanisms.
