UPVC, or PVC, stands for polyvinyl chloride, and was invented by Eugen Baumann in 1872. In 1913, another German, Friedrich Klatte, developed a "new method of the polymerisation of vinyl chloride using sunlight." However, PVC was not considered until 1926, when an employee at BF Goodrich, Waldo Lonsbury Semon, created a plasticised version of PVC. His intention was to create an "unsaturated polymer that could bond rubber to metal." Nowadays, Semon's invention is applied to door handles.
