In the United States, PCBs were commercially manufactured from 1929 until production was banned in 1979 by the Toxic Substances Control Act (TSCA). Pigments, dyes and carbonless copy paper.Plasticizers in paints, plastics and rubber products.Electrical, heat transfer and hydraulic equipment.Due to their non-flammability, chemical stability, high boiling point and electrical insulating properties, PCBs were used in hundreds of industrial and commercial applications including: They have a range of toxicity and vary in consistency from thin, light-colored liquids to yellow or black waxy solids. PCBs were domestically manufactured from 1929 until manufacturing was banned in 1979. PCBs belong to a broad family of man-made organic chemicals known as chlorinated hydrocarbons.
PCBs have no known taste or smell, and range in consistency from an oil to a waxy solid. The number of chlorine atoms and their location in a PCB molecule determine many of its physical and chemical properties. PCBs are a group of man-made organic chemicals consisting of carbon, hydrogen and chlorine atoms. PCBs Revisions to Manifesting Regulations.
