Halogen-containing flame retardants that contain elements such as Cl, Br, F, flame retardant, halogen flame retardant include phosphorus series flame retardant, an inorganic flame retardant of magnesium hydroxide, aluminum hydroxide, zinc borate, etc., in addition Halogenflame retardants include intumescent flame retardant and special purpose flame retardant. A halogen-containing flame retardant is a flame retardant in plastics and rubber materials most widely used fire retardant products, mainly for the organic flame retardants, inert chemical nature, with the plastic in a good compatibility, good flame-retardant effect, the use of low cost, many features are not a substitute for other flame retardants. EU Rosh Directive think octa halogen-containing flame retardants and five PBDEs combustion to dioxins (carcinogens), included in the prohibition of the use of directory, decabromodiphenyl ether is not as controversial as proposed the use of flame retardants. However, most of the halogen-containing flame retardants have not been completely prohibit the use of, the fact is, it is difficult to find a truly completely replace its products. As for harm, sometimes seem alarmist, our country has no restrictions of the use of decabromodiphenyl ether flame retardants. Its harmfulness may not be as legendary so terrible, flame retardants compared to natural hazards and human fire trivial.
