Flame retardants are also not effective when a fire is fully engaged. There is no universal additive for all plastics, rather each flame retardant is specific to a particular polymer and a particular flammability test. To understand how flame retardants work, it is necessary to understand how materials burn.

During combustion, flame retardant additives react with the burning polymer in the vapor phase to disrupt the production of free radicals at a molecular level, thereby shutting down the combustion process. This mechanism is commonly used with halogenated flame retardant systems. Solid Phase Char-Formation Mechanism
