This paper aims to study the influence of additives on the thermal behaviour of
polyvinyl chloride (PVC) products depending on using Differential Scanning
Calorimetry (DSC). DSC was used to determine glass transition temperature (Tg),
maximum processing temperature (Tp) and degree of gelation of PVC products. PVC
products used in this paper include PVC powder standard , PVC drinking water pipe,
PVC draining water pipe, USA PVC adhesive, commercial PVC adhesive and USA
CPVC adhesive. The results show that higher Tg and processing temperature (Tp) are
observed in PVC pipes. While, greater degree of gelation are seen in PVC adhesive.
