Rigid PVC (PolyVinylChloride)
Rigid PVC is one of the oldest thermoplastics in existence today. In 1912 German chemists F.Klatte and E.Zacharias were granted a patent for the process of manufacturing vinyl chloride monomer by addition of hydrogen chloride to acetylene, although full-scale production did not start until 1938. PVC is made up from carbon, hydrogen and approximately 50% by weight chlorine.
