What is Tetrabromobisphenol A


Tetrabromobisphenol A (TBBPA), commonly known as octabromoether, is a relatively common bromine flame retardant. As early as 2003, it has attracted the attention of the world's Greenpeace organization. At that time, Greenpeace commissioned the Dutch TNO laboratory to conduct an electronic product test, which involved 19 samples including TV sets, mobile phones, and OCs. Among them, the PC products selected are the top three manufacturers in the world: Hewlett-Packard, IBM, and Dell. As a result, the proportion of brominated flame retardants in a computer model of Pavilion250NL from Hewlett-Packard is higher than that of similar products of other companies tested, and the content of tetrabromobisphenol A (TBBA) reaches 20% of the weight of the plastic components of this product. The highest among PC test samples.
 
Hexabromocyclododecane (HBCDD) is an additive flame retardant with high bromine content. It has the advantages of high flame retardant efficiency, wide application, and sometimes does not need to use antimony synergists. After PBB/PBDE was restricted, it was widely used as a substitute. Although HBCDD has an excellent flame retardant effect, it poses a potential long-term hazard to humans and the environment. International environmental protection organizations have included it in the list of "Stockholm Convention on Persistent Organic Pollutants" (POPs); at present, all countries in the world, especially developed countries, are consciously controlling the production and emission of HBCDD.
 
Tetrabromobisphenol A (TBBPA) and hexabromocyclododecane (HBCDD) are common bromine flame retardants, and their pollution hazards are obvious. Its contamination ability is high and persistent, and it is very easy to accumulate in the human body. There are three main hazards: first, long-term exposure to brominated flame retardants can hinder brain and bone development; second, when it is incinerated, it will release brominated dioxins and furans, both of which are highly carcinogenic. Substances; third, it also seriously harms the hormonal system.
