Melamine polyphosphate

Melamine polyphosphate (CAS 20208-95-1 ) is a halogen-free flame retardant used across polymer and coating systems where low smoke emission and thermal stability are required.

It functions by releasing non-combustible gases and forming a char barrier upon exposure to heat, interrupting the combustion cycle in finished materials for industrial use.

In glass-fiber-reinforced polyamides and polyesters, it delivers UL 94 V-0 ratings at competitive loading levels, making it a preferred choice for electrical connectors and housings.

Automotive under-hood components and intumescent coating formulations for steel and timber structures incorporate it as the acid source and blowing agent precursor for safety.

Textile and paper back-coating systems use it to impart durable flame retardancy without halogenated compounds, supporting compliance with EN 13501 and similar global standards.

In epoxy-based printed circuit board laminates, it contributes to flame retardancy while maintaining the electrical insulation performance required by IPC specifications for electronics.

The product is supplied as a white powder in various particle size distributions suited to compounding and coating applications. Standard grades are differentiated by phosphorus content.

Nitrogen content and thermal stability thresholds match specific polymer processing temperatures. Both technical and high-purity grades are available with full TGA data and test reports.
