Bisphenol A, BPA, C15H16O2 molecule. It is precursor to polycarbonate plastics and epoxy resins. Molecular model. 3D rendering. 3D illustration
A molecular model of Bisphenol A or BPA.  It is a common building block in the production of many epoxy resins and plastics including polycarbonate plastic. As such it is present in a huge range of food packaging and household products. There are now concerns about its health effects, particularly its effect on children, infants and fetuses.   Isolated on white.
