Melamine (Gas Source) Flame Retardant / IFR Blowing Agent

Featured inFlame Retardants

Melamine is the standard gas source (blowing agent) component in the classic APP/PER/MEL ternary intumescent flame retardant system used in structural steel fireproofing coatings, halogen-free polyolefin FR compounds, and passive fire protection products. Upon decomposition at 250–300 °C, melamine releases large volumes of NH3 and CO2 that inflate the char formed by the acid source/carbon source reaction, creating a thick insulating foam layer. The high nitrogen content (66.6%) also contributes to gas-phase flame inhibition.
