Application of aluminum hydroxide in cable material

In the cable material industry, aluminum hydroxide mainly plays a role in flame retardancy, smoke suppression and reducing the amount of corrosive gas generated when the material is burned. So how does aluminum hydroxide achieve its flame retardant and anti-inflammatory effects? One hand, because aluminum hydroxide is a kind of hydroxide containing water, the chemical formula of the substance itself contains a certain amount of water. During the temperature increase, the aluminum hydroxide will continue to absorb heat, reduce the temperature of the cable and prevent burning; Another hand, because alumina has a larger surface area, it can absorb smoke particles and inhibit the generation of smoke to achieve the purpose of smoke elimination.
