The advantages of aluminum hydroxide as a flame retardant
1) Outstanding endothermic cooling effect during the reaction, The content of crystal water in aluminum hydroxide is as high as 34.46%. When the surrounding temperature rises above 300°C, all of this water will precipitate. Due to the large specific heat of water, a large amount of heat energy needs to be drawn from the surroundings when it turns into water vapor. 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 generated.
3) It has a reinforcing effect on rubber and other products When the particle size of aluminum hydroxide is as low as quasi-nanometer level (diameter≤2μm), it can also have a reinforcing effect on rubber and other products as the particle size is smaller, the reinforcing effect is stronger and the flame retardant effect is better.
4) Sufficient resources
The preparation and processing technology of aluminum hydroxide is relatively mature and easy to obtain at a low price.
