WebWhat is Polyvinyl Chloride (PVC)? PVC is Polyvinyl Chloride. This is a plastic that has the following chemical formula: CH2=CHCl (see picture on the right). Plastic covers a wide rage of synthetic or semi-synthetic polymerization products (i.e. long-chain carbon-based "organic" molecules) which name refers to the fact that in their semi-liquid ... WebHard carbon is produced by heating lignin and cellulosic biomass-based carbonaceous precursors to approximately 1000 °C in the absence of oxygen. Other precursors, such as polyvinyl chloride (PVC) and petroleum coke, produce soft carbon, or graphitizing carbon. Soft carbon can be readily converted to graphite by heating to 3000 °C.
