Flammability of pvc
Web“Flammability” is referred as capability of ignition, flame spreading and heat generation. Flammability of Plastics is a result of the chemical nature of the carbon and hydrogen atoms in polymer chain, which are readily burned … WebNov 25, 2024 · However, Wang et al. [ 9, 10] investigated the pyrolysis and flammability of new and aged polyvinyl chloride (PVC) sheaths of cables. They found that an aged sheath generally pyrolyzes and combusts more weakly and incompletely compared to the new one.
