The objective of the present work is to provides a comprehensive overview on the thermal analysis of the virgin high-density polyethylene (VHDPE) graded AD60 material by means of a differential scanning calorimetry (DSC) equipments. In order to verify possible transformations in its molecular structure and change of phases present with the variation of temperature over time. Past literature results reported the testing-analysis of the samples which was carried out through 3 distinct cycles separated into 3 stages, the first of which the material will undergo a heating of the ambient temperature up to 178°C, at a rate of 10°C/min, the second stage a cooling from the temperature of 178°C at a temperature of 43°C, with a rate of 10°/min, and the third stage the test body will undergo a new heating from 43°C to 184°C with a rate of 10°C/min. As revealed from in-depth studies, results obtained from the thermograms for the seven samples of the high-density polyethylene for the three required cycles, showed approximate values, with variations in centesimal scales that can be disregarded if the slight variations have been analyzed in the air pressure that the equipment can present. With this, it was possible to conclude the values of the parameters of the crystallization temperature (Tc), the percentage of crystallinity (% C), Melt Temperature (Tm) and melting enthalpy change (ΔHfm).
