Bisphenol A (BPA) is a commonly used industrial chemical and is used as a building block (monomer) for the manufacture of polycarbonate plastic (PC) and epoxy resins. Polycarbonates are used to manufacture synthetic glass, CD and DVD blanks, as well as food containers such as cookware for microwave ovens, water dispensers or kettles. BPA-based epoxy resins are used in large quantities in the construction sector (boat and mould-making, pipework). Epoxy resins come into contact with food mainly in the form of protective coatings used in food tins and drinks cans. One additional use of BPA relevant to our everyday lives is the thermal paper used, for example, in the manufacture of till receipts and tickets. In addition, BPA is used in dental sealants, paint coatings, surface coatings, adhesives and electrical appliances.
