Melamine polyphosphate

Melamine polyphosphate (CAS 20208-95-1) is a halogen-free flame retardant for polymer and coating systems requiring low smoke emission and thermal stability.

Where is Melamine polyphosphate used?

• Glass-fiber-reinforced polyamides and polyesters: UL 94 V-0 ratings at competitive loading levels for electrical connectors and housings
• Automotive under-hood components and intumescent coatings for steel and timber: acid source and blowing agent precursor
• Textile and paper back-coating: durable flame retardancy without halogenated compounds, supporting EN 13501 compliance
• Epoxy-based printed circuit board laminates: flame retardancy while maintaining electrical insulation performance per IPC specifications
• It releases non-combustible gases and forms a char barrier upon heat exposure, interrupting the combustion cycle.

Commercial specifications

• White powder in various particle size distributions
• Standard grades differentiated by phosphorus content
• Nitrogen content and thermal stability thresholds match polymer processing temperatures
• Technical and high-purity grades with TGA data and test reports
