PVC Lump

Polyvinyl chloride (PVC) is one of the earliest man-made synthetic materials and has the longest history in industrial production. In 1835, for the first time Henri Regnault synthesized vinyl chloride (VC), the main raw material to make PVC. Polyvinyl chloride was first observed in 1872 by Baumann when exposed to vinyl test tubes containing vinylcloride in sunlight, the resulting product had a white powder form and its chemical properties were not determined.
