Melamine Homologs

Melamine homologues (melam, melem, melon) have higher thermal stability compared to pure melamine and melamine cyanurate. If processing temperatures are well above the temperature range of Melamine Cyanurate (320°C) this may result in mould deposit. Melamine homologues offer an alternative nitrogen source that can be used under such extreme conditions. Melam, melem and melon are believed to act in general in the same way as melamine only at higher temperature.
