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. WebPVC vs uPVC comparison. Regular PVC (polyvinyl chloride) is a common, strong but lightweight plastic used in construction. It is made softer and more flexible by the addition of plasticizers. If no plasticizers are added, it is known as …
