Bisphenol a terephthalate
As a result of the presence of BPA in plastics and other commonplace materials, most people are frequently exposed to trace levels of BPA. The primary source of human exposure is via food, as epoxy and PVC are used to line the inside of food cans to prevent corrosion of the metal by acidic foodstuffs. Polycarbonate drinks containers are also a source of exposure, although mos… WebBromination of BPA forms tetrabromobisphenol A (TBBPA), which is mainly used as a reactive component of polymers, meaning that it is incorporated into the polymer backbone. It is used to prepare fire-resistant polycarbonates by replacing some bisphenol A. A lower grade of TBBPA is used to prepare epoxy resins, used in printed circuit boards.
