Chemical Mechanisms & Reaction Pathways

Aluminum hydroxide provides exceptional flame retardancy through endothermic decomposition and water release mechanisms, delivering comprehensive fire protection with excellent smoke suppression and non-toxic gas generation properties.

Endothermic Decomposition

Thermal breakdown: 2Al(OH)₃ → Al₂O₃ + 3H₂O (heat absorption)

Cooling effect reduces combustion temperature and flame spread
Water Release

Steam generation dilutes combustible gases and reduces oxygen concentration

Physical barrier formation inhibits flame propagation
Char Formation

Protective alumina layer formation provides thermal insulation barrier

Enhanced structural integrity during fire exposure
Smoke Suppression

Reduced smoke and toxic gas generation compared to halogenated systems

Environmentally friendly flame retardation mechanism
