PBDEs are toxic additives that increase what quality in materials?

Explanation:
PBDEs are used as flame retardants, added to materials to slow ignition and hinder flame spread, thereby increasing fire resistance. In a fire, they release bromine-containing species that interfere with the flame’s chemical reactions, scavenging reactive radicals and promoting a protective char layer. This combination reduces heat release and buys time for safety actions. They are not added to improve electrical insulation, elasticity, or thermal conductivity, so the primary effect is enhanced fire resistance.
