Fine Aluminium Hydroxide Flame Retardant and Smoke Suppression Performance

Micron Powder Aluminium Hydroxide in the field of industrial applications is increasing, a big reason lies in its flame retardant and smoke suppression performance.

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:


1, Endothermic effect: at 200-350 ° C dehydration endothermic, inhibit the polymer temperature rise.
2, Carbonation: fine aluminium hydroxide flame retardant in the combustion conditions to produce a strong dehydration of substances, so that carbon carbide and easy to produce flammable volatile, thereby preventing the spread of the flame.
3, Cover the role: Precipitated Aluminium Hydroxide dehydration in the combustible surface after the formation of AL2O3 protective film. It could isolate oxygen to prevent continued combustion.

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.
