Description
Melamine cyanurate is a salt of melamine and cyanuric acid. It has a higher thermal stability than pure melamine, remaining stable up to about 320ºC. For this reason, Melamine cyanurate is often applied in polymers with higher processing temperatures. Above 320ºC, it undergoes endothermic decomposition to melamine and cyanuric acid, acting as a heat sink in the process. The vaporized melamine acts as an inert gas source diluting the oxygen and the fuel gases present at the point of combustion. The released cyanuric acid reacts with the polymer to form a char inhibiting the release of free radical gasses into the oxygen phase. Examples of suitable polymers: all nitrogenbased polymers such as polyamide 66, 6, 11, 12, thermoplastic polyurethane and polyurethane.
