The aim of this work is to elaborate mathematical models for the calculation of the experimental thermal properties of PVC tubes as a function of the shell powder dosage. We performed the TGA/DSC of unloaded PVC tubes and PVC tubes loaded with 12.54%, 32.03% and 51.01% of palm kernel shell powder using a TG coupled DSC apparatus of LENSEI brand. We obtained the TG/DSC thermograms and their recording which gave us the results of the thermal characteristics of the tubes. From those results, we obtained that the phase transition temperatures vary with the dosage. We have represented the curves of heat absorption as a function of the mass decrease. Keywords: materials characterization, thermogravimetric analysis, thermodifferential analysis, thermal characterization, modeling of thermal parameters.
