Product Description

Product Description

The flame-retardant mechanism of aluminum hydroxide is: it decomposes at 200-300ºC, and dehydration reaction occurs after decomposition, which absorbs a large amount of heat on the surface of polymer materials, which can reduce the surface temperature of burning materials; at the same time, dehydration produces a large amount of water vapor, which dilutes combustible gas and oxygen Concentration; Its decomposition residues Al2O3 are dense oxides, which are deposited on the surface of the material to limit the generation of combustible gas,so it can play the role of heat insulation and oxygen isolation and achieve the effect of suppressing smoke; And aluminum hydroxide can absorb acid gas . Aluminum hydroxide has a moderate price and is the most widely used  flame retardant filler.
