Aluminum hydroxide is the largest and most widely used inorganic flame retardant additives. Flame retardant principle is endothermic decomposition into alumina and water, decomposition products are safe, non-toxic, non-corrosive substances, the endothermic reaction in the combustion process of the polymer to absorb a large amount of heat, so as to protect the polymer from rapid decomposition, delay the formation of flammable by-products, the resulting water vapor to replace oxygen, play a similar inert The role of the gas; the formation of a protective layer of alumina and carbonized products on the surface of the polymer to further inhibit combustion, this protective layer can also reduce the smoke density by adsorbing soot particles.
