Phosphorus Flame Retardants
Phosphorus Flame Retardants not only react with the radicals like BFRs, but are also able to act in the condensed phase by enhancing char formation, yielding intumescence (foaming-up), or formation of inorganic glasses. In fact, PFRs are most commonly known as char formers, because during the burning process they produce phosphoric acids, which, reacting with the substrate, produce a char that acts as a protection of the substrate itself. The most used PFRs are as the table below, their main area of application is in polyamides(PA), polyesters(PET/PBT), polyolefins, and polystyrene (PS) formulations, especially in electrical and electronic insulation components.
