Halogenated flame retardants generally have the lowest usage rate. • Inorganic flame retardants dilute the available plastic fuel, dilute the incendiary gases, and absorb energy via endothermic reactions, but must be used at very high dosages. • Intumescent flame retardants form a protective layer upon combustion, eliminating the polymer fuel source.
