Overview
TBBP-A is one of the most commonly used brominated flame retardants globally. The main application is in polymers where the compound is incorporated in the polymer structure.
Commercial grade TBBP-a will have a varying degree of bromination i.e. not all will be tetra-brominated
TBBP-A have been registered under REACH
Toxicity
TBBP-A has a low potential for toxicity. Human exposure to the compounds through food and water is low and the compound is rapidly excreted in all mammals. There has been some initial concern that TBBP-A may have a potential as an endocrine disruptor, however this has since been proven not to be correct.
