Why does aluminum hydroxide have flame retardant function?
Aluminum hydroxide is an additive type flame retardant. When subjected to a high temperature of 235 degrees, a decomposition reaction occurs to produce water and alumina. The change of water into water vapor will take away a lot of heat and reduce the temperature of the synthetic material. The resulting alumina, which has an extremely high surface area, prevents contact between oxygen and organics, resulting in an interruption of combustion.
It should be noted that aluminum hydroxide is an additive flame retardant, what does that mean? That is to say: in plastic synthetic materials, it does not play a major flame retardant role, to reach the V0 level, it also needs to be used with other flame retardants.
Then someone said again, since you can't achieve V0 effect by using it alone, I won't have. Wrong, the purpose of using aluminum hydroxide is to reduce the use of other flame retardants (other flame retardants are expensive), so as to achieve the purpose of reducing product costs.
Aluminum hydroxide is an inorganic flame retardant additive with large amount and wide application. Aluminum hydroxide as a flame retardant can not only flame retardant, but also can prevent smoke, do not produce dripping, do not produce toxic gases, therefore, access to a wider range of applications, the use is also increasing year by year. Scope of use: thermosetting plastics, thermoplastics, synthetic rubber, coatings and building materials and other industries.
