Has nothing to do with the halogen-containing flame retardants is environmentally friendly, brominated flame retardants family includes more than 70 different types of chemical substances, and they have many different features. Few halogen-containing flame retardants environmental risk, but does not represent a flame retardant flame retardant family as a whole. Each chemical has its own characteristics, not simply on the basis of chemical substances containing certain elements which classified it as a family, that this family has a common set of properties.
Flame retardant's role is to prevent the occurrence of fire, delaying flashover in the coming time, gives more opportunities for escape. The fire itself is toxic, fire the main cause of death was carbon monoxide, polycyclic aromatic hydrocarbons and hydrogen cyanide and other toxic gases. Regardless of whether you use flame retardants, brominated flame retardants, produce toxic gases. So, did not increase toxicity of fire brominated flame retardant and fire suppression, reducing toxic gas point of view, credited for environmental protection.
Meanwhile, United States toxic substances Control Act (TSCA), European regulation of the registration, evaluation, authorisation and restriction of chemicals (REACH) as well as a number of other laws and regulations in the world were, including flame retardant chemicals have strict supervision. After a rigorous evaluation, most of brominated flame retardants can be safely used in consumer products. It is worth mentioning that, BSEF in brominated flame retardants, tetrabromo Bisphenol a study a step further, we find that in the area of environmental protection and human health to meet more demanding requirements than these regulations. For example, when used in printed circuit boards, and tetrabromo Bisphenol a is reactive flame retardants, brominated epoxy resins can be generated eventually. This circuit board for chemical exposure risk to the public is very low, very high degree of security.
Not all brominated flame retardants are persistent organic pollutants (POPs). Currently still in the production and marketing of brominated flame retardants only one POPs, hexabromo 12-hexabromocyclododecane (HBCD). United Nations [Twitter] Environment Programme (UNEP) in 2013, it is officially classified as the Stockholm Convention POPs.
