Brominated Flame Retardant 6
Brominated Flame Retardant 6 : Testing for BFR in Plastics: Until recently testing for BFR has been cumbersome. Cycle time, cost and level of expertise required for the test engineer has precluded the implementation of any screening of plastic components in a manufacturing or in a product qualification/validation environment. Recently, with the introduction of a new analytical instrument IA-Mass, screening of plastic material alongside a manufacturing line became possible. A five minute detection cycle and a 20 minute quantification cycle is available to test and to qualify plastic parts as they reach the assembly line. IA-Mass identifies the presence of bromine (PBB, PBDE, and some others), but cannot characterize all the BFRs present in the plastic matrix. In February 2009, the Institute for Reference Materials and Measurements (IRMM) released two certified reference materials (CRMs) to help analytical laboratories better detect two classes of flame retardants, namely polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs). The two reference materials were custom made to contain all relevant PBDEs and PBBs at levels close to the legal limit set out in the RoHS Directive of 1 g/kg for the sum of PBBs and PBDEs. (6) Environmental and safety issues: Many brominated chemicals are coming under increasing criticism in their use in household furnishings and where children would come into contact with them. Some believe the chemicals, including PBDE could have harmful effects on humans and animals. Increasing concern has prompted some European countries to ban some of them, following the precautionary principle more common in Europe. They are lipophilic and bioaccumulative. BFRs have been found in people all over the world. Brominated flame retardants are persistent, bioaccumulative, and toxic to both humans and the environment and are suspected of causing neurobehavioral effects and endocrine disruption
