While intumescence is a leading scientific endeavor in fire protection engineering in modern times, its discovery dates back to British Patent 551, granted in 1735 to Obadiah Wyld , which set the precedent for the boom seen in the 1970s–1980s flame retardant (FR) industry—which consequently lead to the current fast-replacement-based industry of fire protection additives. FRs can be qualified as either: additive, those assimilated into the polymer …


2014-1-1 · ISO defines flame retardant as “substance added, or a treatment applied, to a material in order to suppress or delay the appearance of a flame and/or reduce the flame-spread rate.” Fire retardant is normally considered to be synonymous with “flame retardant,” but ISO declares it to be either a synonym of “flame retardant,” or a “substance added, or a treatment applied, to a material in order to …


The detection of flame retardants is critical for the recycling of polymers.
