Melamine Cyanurate is a kind of salt synthesized from melamine and cyanuric acid, and belongs to phosphorus-nitrogen flame retardant. Two types (powdered and granulated) of MCA can be supplied to meet the users' requirements. The vaporized melamine acts as an inert gas source diluting the oxygen and the fuel gases present at the point of combustion. The cyanuric acid acts to decomposed the polymer thus rapidly removing it from the combustion source. In this case, there are three types of flame retardant mechanisms at play.

Melamine Cyanurate is a halogen-free flame retardant for polyamide. Melamine Cyanurate has established itself as the flame retardant of choice to achieve UL94 V-0 especially for unfilled polyamide 6 and 6, 6. Some of its attributes include cost effectiveness, excellent electrical and mechanical properties and colorability, Non-blooming, low smoke generation, and low corrosivity. It is also a safe material to use from a handling standpoint, as well as in fire situations in compounds, health, safety, and compatible with environment; A good balance between flame-retardant effectiveness and thermal stability of Melamine Cyanurate provides for easy processing at the compounding stage.
