Aluminum hydroxide is currently the largest and most widely used inorganic flame-retardant additive. It can not only be flame-retardant, but also can inhibit smoke and absorb poisonous gases such as hydrogen halide. Therefore, it has been widely used.
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.Specification

Application:
Aluminum hydroxide is the most widely used inorganic flame retardant, as a flame retardant not only can prevent flame retardant, and can prevent smoke, do not produce drops, do not produce toxic gas, therefore, more widely used, the amount of use is increasing year by year .Scope of use: low smoke halogen free cable materials, silicone rubber, thermosetting plastics, thermoplastics, synthetic rubber, paint, rubber insulation materials and building materials and other industries.
