The use of flame-retardant surface treatment can effectively prevent future material combustion by positioning all flame-retardant materials where the chain reaction is most likely to be stopped. Fig. 15 (f) and (g) show that FRC begins to degrade at around 300 °C, at which point it starts to operate as a flame retardant.
About Flame Retardants
Flame retardants are one of the key reasons these failures may not escalate into something more serious like a home or office fire. Flame retardants not only reduce the risk of a fire starting, but also the risk of the fire spreading — leaving more time for people to escape and firefighters to respond.
