Why do we need stabilizers? PVC degradation mechanism
PVC degradation is the result of dehydrochlorination reaction in which hydrogen chloride (HCl) is split off. Without PVC stabilizers, free HCl generation accelerates the dehydrochlorination process, resulting in a chain reaction called the Zipper reaction. HCl and conjugated double bond (a single bond between two or more double bonds) are formed, resulting in PVC with…
