Polychlorinated biphenyl (PCB) is a group of synthetic chemicals that was manufactured for use in dielectric fluids, and as insulators for transformers and capacitors. PCBs were considered the perfect oil. They were found to be very useful for preventing fires and explosions, and also for hydraulic fluids, casting wax, carbonless carbon paper, compressors, heat transfer systems, plasticizers, pigments, adhesives, liquid cooled electric motors, fluorescent light ballasts and so on.

The most highly favored PCBs were the ones with the most chlorines, which ...
