2001-07-25 · The PBDE flame retardants are used in resins and polymers . DeBDE and TBBPA are the two most used of the PBDE flame retardants, the detail of which is given in DTI (1999) report. The major uses are in high impact polystyrene, flexible polyurethane foam, textile coatings (not clothing), wire and cable insulation, electrical and electronic connectors and other interior parts ( Table 2 , Table 3 ).

Polybrominated diphenyl ether (PBDE), for example, is a common flame retardant used to reduce the risk of fire in a wide variety of products. PBDEs are present

Americansare exposed to PBDEs on a daily basis. The chemicals are used in plastics and foams and added to products phones, furniture and electronics to make them flame retardant. Bromine Flame Retardants (BFRs) are the most prolific flame retardant used for their vapor phase inhibition properties. Bromine in particular is used because as it is heated the compound releases active bromine atoms into the gas phase, before the material reaches its ignition temperature.

They are added to many household items and consumer products. There is controversy as to whether the benefits of flame retardants are as significant as is claimed. In the United States, PBDE concentrations are rising, especially in children. Toddlers and preschoolers have 3 times higher blood concentrations of flame retardants than their mothers – an average of 62 parts per billion.

Flame retardants are used to make sure that a wide range of different PBDE substances have been phased out by EFRA companies since Many PBDEs are banned or have been phased out of use, but that doesn't mean that *other* harmful flame retardants aren't still in use. Mostly, mattress cadmium, chromium hexavalent, flame retardant (polybromobiphenyles.
