A novel method for determining the level of dehydrochlorination, i.e., the conversion of degradation from the conductivity curve of plasticized poly(vinyl chloride) (PVC) containing heavy metal-free agent, has been used. The novel method was introduced in this article to evaluate the thermal stability of PVC by dehydrochlorination shows more reproducibility for measured results than the standard method, which depends on the conductivity only. The novel method was used to measure thermal degradation in a new generation of thermal stabilizing heavy metal-free additive added to plasticized PVC, which is Oxydtron® (a nanocement additive). Plasticized PVC containing Oxydtron is our new candidate to replace conventional stabilizers or at least increase their efficiency. The primary use of this new material is in the cable grade industry and construction applications. The basic principle of our novel method is based on converting the conductivity data obtained by the conventional or standard method to HCl concentration. The data analysis graph will have two curves instead of the one conductivity curve, representing the conversion and HCl concentration. In this study, a comparison was made between the results of the novel method with the results obtained from the conventional or standard method. In contrast to the standard method, it describes better the process, particularly in the case of PVC compounds. This method's designed computer program shows a good agreement with the discoloration and initial color changes.
