Aluminium Hydroxide ,short for ATH. It is white solid powder .The chemical composition of aluminum hydroxide is Al2O3 2H2O or Al (OH) 3, with molecular weight of 78. It is an amphoteric compound with certain activity. It can be dissolved in acid and alkali to form aluminum salt and aluminate. When heated to 200, it begins to decompose, rapidly dehydrate and presents endothermic reaction. So Aluminium Hydroxide could be used as a fire retardant filler for polymer applications. It is selected for these applications because it is colorless (like most polymers), inexpensive, and has good fire retardant properties. It decomposes at about 180 °C (356 °F), absorbing a considerable amount of heat in the process and giving off water vapour. In addition to behaving as a fire retardant, it is very effective as a smoke suppressant in a wide range of polymers, most especially in polyesters, acrylics, ethylene vinyl acetate, epoxies, PVC and rubber.
