Flame retardancy mechanisms According to their specific mechanisms, fire retardants interrupt polymer pyrolysis in one or more steps. Three of the most common flame retardancy mechanisms are described in previous studies. Gas phase inhibition mechanism, where the FRs react with the polymer under combustion in the gas phase with hydroxyl or oxygen agents at the molecular level and extinguish the combustion…

The importance of flame retardants In order to meet fire safety requirements and diminish fire hazards, different solutions have been developed. Various chemical and physical strategies have evolved to prevent polymers from burning or to lower the heat release amount. Recently, flame retardants (FRs) have been widely recognized as fire safety tools capable of lowering the number of fire injuries and death. The t…

Fire hazard losses Fire hazard is a general term that is a combination of different factors, including ignitability, amount of heat release, ease of extinction, weight-loss, flame spread, smoke index, and toxicity. Modern life is surrounded by a wide variety of readily combustible materials, such as, cellulosic materials and man-made polymers. Synthetic polymers alone may not be a fire hazard, b…
