PVC or its chemical name, polyvinyl chloride, is a popular thermoplastic (a plastic that becomes liquid when heated and a brittle and glassy when cooled) polymer. PVC is one of the most valuable products in the chemical industry. It is cheap, durable, and easy to use. PVC is used in a wide variety of products, such as building material (instead of wood, concrete or steel), vinyl siding, magnetic stripe cards, window profiles, vinyl records, figurines, toys, pipes, furniture and more. In its softer forms, it is used is products such as clothing, upholstery, flexible hoses, tubing, flooring, roofing and electrical cable insulation. PVC was first discovered accidentally in 1835 by French chemist and physicist, Henri Victor Regnault. PVC had no useful purposes because it was too brittle. It was not until 1926, when Waldo Semon and the B.F. Goodrich Company developed a method to soften PVC by blending it with other substances to make it flexible and allow its use in many commercial products.
