Halogenated flame retardants are chemical compounds that contain halogens, such as bromine, chlorine, or fluorine. They are added to materials like plastics, textiles, and electronics to reduce the risk of fire. By slowing down the spread of flames, these substances help protect lives and property in case of a fire. These flame retardants work by interfering with the combustion process, either by releasing halogen gases that inhibit flame growth or by forming a protective char layer. However, concerns have been raised about their potential environmental and health impacts, leading to increased regulation and the search for safer alternatives.
