To realize combustion, three factors (comburent, combustible and fire source) need to exist at the same time, and the combustion process is divided into heating, decomposition, ignition, burning and spreading. If any link is removed, or if we try to control the combustion process in the embryonic stage of heating and decomposition, we can effectively avoid fire.

In the way of preventing flame burning, different types of flame retardants have their own "coup", some prevent combustibles from generating combustible gas by absorbing heat, and some form a dense covering layer on the surface of combustibles, so as to isolate the contact between combustibles and oxygen, while others capture the free radicals involved in combustion reaction laterally, and chickens achieve the purpose of inhibiting the chain reaction of free radicals ...

While tetrabromobisphenol Ap will start to decompose when heated to 115℃ to 120℃. When the decomposition temperature of polymer materials is the same or similar, tetrabromobisphenol A will also volatilize and enter the meteorological combustion area together with the thermal decomposition products. Tetrabromobisphenol A can quickly capture the free radicals in the meteorological combustion area, thus inhibiting the free radical chain reaction and preventing the flame propagation, and then obviously reducing the reaction speed until stopping the combustion process of objects.
