1）The endothermic cooling effect of the reaction process is prominent: the crystal water content in aluminum hydroxide is as high as 34.46%, and when the ambient temperature rises above 300℃, all of these moisture are precipitated. Because of its high specific heat, water absorbs a lot of heat from its surroundings when it turns into steam. Magnesium hydroxide also contains crystal water, but the water content is only 30.6%. Moreover, magnesium hydroxide is not conducive to dielectric properties, and its applicability is not as good as aluminum hydroxide.

2) Environmental protection and safety in the flame retardant process, no toxic gas will be produced.

3) It has a reinforcing effect on rubber and other products. When the particle size of aluminum hydroxide is low to quasi-nano level (diameter ≤2μm), it can also have a reinforcing effect on rubber and other products, and the smaller the particle size, the stronger the reinforcing effect, and the better the flame retardant effect.

4) sufficient resources aluminum hydroxide preparation process is relatively mature, easy to obtain cheap.
