الملخص الانجليزي
What are the structural changes in the PVC layer located directly under the flame zone which is exposed to high temperatures without burning? We will try to explain in this article what actually happens in this layer, which we called heat affected zone. The layers were tested both with and without antimony trioxide (ATO or Sb2O3) flame retardant additive. Results obtained from Scanning electron microscopy (SEM) for the heat affected zone of the samples after Limited oxygen index (L.O.I) test and compared with the samples before this test showed that there was a significant decrease in the chlorine content in the PVC structure accompanied by a significant increase in the carbon content. We suppose that this early dehydrochlorination improves the efficiency of Sb2O3.
