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.
Brominated 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).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.
