A flame retardant is a chemical substance that is added to materials during their manufacturing process in order to both reduce the likelihood of the finished product catching fire and slow down combustion. Source: GreenFacts.
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.rominated flame retardants (BFRs) are organobromide compounds that have an inhibitory effect on combustion chemistry and tend to reduce the flammability of products containing them. Of all the commercialized chemical flame retardants, the brominated variety are widely used (19.7% of the market).
