Ammonium Polyphosphate
Ammonium polyphosphate (CAS 68333-79-9) is a polymeric phosphorus-nitrogen flame retardant with the repeat unit (NH₄PO₃)ₙ. It is a white powder used in intumescent coatings, plastics and textiles. Chain length and molecular weight vary by grade; specifications depend on phosphorus and nitrogen content.
• Intumescent flame retardants: acid source in expandable coatings.
• Polymer flame retardancy: halogen-free additive in polyolefins and epoxies.
• Textile treatment: durable flame resistance.
• Phosphorus-nitrogen flame retardant: where halogen-free systems are preferred.
