Vinyl is a plasticized variation of Polyvinyl chloride (PVC). Although PVC is hard, with the addition of plasticizers it can be made pliable enough, for example, to coat fabrics in any thickness.
In 1926, Waldo L. Semon, a scientist working for BF Goodrich, accidentally discovered this compound while trying to form a synthetic rubber. At first he thought that the rubbery gel he created would work as a bonding agent to adhere rubber to metal. However, through further experimentation he found he had invented a highly versatile plasticized vinyl that, in the early 2000s, has hundreds of uses.
To present his discovery to the company, Semon applied the gel to curtains, creating a waterproof vinyl-coated shower curtain. It stirred a sensation! Vinyl was quickly adapted to umbrella and raincoat fabrics for its waterproof properties. Vinyl was also used to coat wires. Commercialized in 1931, the new technology was highly successful. During World War II, vinyl was turned to wartime use, and so it wasn't until the 1960s that vinyl again became a fashion item.
