Solved Melting temperature (Tm) of high-density polyethylene

WebThe DSC measures Tg, Tm, and percent crystallinity. The DSC process includes heating the sample at a constant rate (e.g., 10°C per min), and measuring the heat flow of the plastic as it changes from crystalline to amorphous (Tg) or solid to liquid (Tm). The features of the DSC are shown in Fig. 3.8. Fig. 3.8. DSC curve for LDPE. WebMelting temperature (Tm) of high-density polyethylene (HDPE) is approximately 120 °C and the Tm of nylon-6 is approximately 220 °C.
