Unlike organic flame retardants, which capture free radicals in the gas phase, inorganic flame retardants primarily exert their flame-retardant effect through physical endothermic processes, oxygen dilution, char formation, and the formation of a protective layer. They possess advantages such as low smoke, low toxicity, good thermal stability, and relatively low cost, thus occupying an important position in the field of flame retardant polymer materials.
