Uses of bromine. Several important flame retardants, such as tetrabromobisphenol A, are derived from bromine and bromine compounds although there are concerns about the effectiveness of some of them. The flame retardants are, for example, either bonded (chemically) or incorporated physically, into plastics.hile Figure 1 shows data for the worldwide use of bromine, the proportion varies country by country. For example in the US, less (45%) is used to make flame retardants and more (21%) as clear brines for drilling.
