Gas-Phase Mechanisms of Fire Retardants



Gregory T. Linteris


Fire retardants are added to polymers to increase their ignition time and reduce their heat release rates when burning. They are often described as acting either in the condensed-phase or in the gas-phase, with an understanding that often, both modes can be important for a given fire retardant. The purpose of this note is to review the understanding of the mechanisms by which fire retardants act in the gas phase.
