The endothermic dewatering process of ATH Powder delays the combustion of the polymer, slowing the combustion rate while releasing the water vapor, not only diluting the combustion gases, but also the reaction of the condensate phase. Endothermic decomposition of the direct effect of dilution, but also make aluminum hydroxide smoke suppression. The decomposition of the generated alumina together with other carbides to form a flame retardant barrier, it could reduce the burning rate, in order to prevent the spread of the flame.
The flame retardant mechanism of Fine Aluminium Hydroxide is summarized:
4, Dilution: rubber, plastic and resin and other organic polymers filled with ATH Powder, the composite material in the concentration of combustible material decreased; In addition, the decomposition of Aluminium Hydroxide Products after the release of water vapor dilution of flammable gas and the concentration of oxygen, could effectively slow down or prevent burning.
