Product Information of Melamine Pyrophosphate

Chemical Properties of Melamine Pyrophosphate

Melamine Pyrophosphate is produced through the reaction of melamine and pyrophosphoric acid.

It combines:

• Nitrogen flame retardant mechanism from melamine

• Phosphorus flame retardant mechanism from phosphate

Key characteristics:

• Halogen-free flame retardant

• Excellent thermal stability

• Low smoke generation

• Low toxicity

• Good compatibility with polymers

• Promotes char formation

• Environmentally friendly formulation

During combustion, MPP releases inert gases and promotes the formation of a protective carbonized layer, reducing heat transfer and improving flame resistance.
