Melamine phosphate

Melamine phosphate (CAS 41583-09-9) is a halogen-free flame retardant salt produced from the reaction of melamine and phosphoric acid.

Where is Melamine phosphate used?

• Intumescent coatings and paints: acid source component enabling the char-forming reaction that protects structural steel and wood substrates
• Plastics: incorporated into polyolefins, polyamides, and epoxy systems to meet UL 94 and other flame retardancy standards
• Textile and paper: back-coating formulations for flame retardancy certification of upholstery and curtains
• It is also used for industrial fabrics and in rigid and flexible foam systems.

Good to know: It functions by releasing non-combustible gases and forming a protective char layer when exposed to heat, interrupting combustion in polymer systems and coatings.

Commercial specifications
