Interpreting Unexpected Events and Transitions in DSC Results

Relieve the internal stresses in the material by heating it to at least 25°C above the T g and then quench cooling it to a temperature below the T g. Figure 9 shows the same material as in Figure 8 after curing at 200°C and then quench cooling to 25°C. Figure 11: DSC scan of PET after quench cooling

Heating and Cooling Curves (The Basics)

Cooling curves are the opposite. They show how the temperature changes as a substance is cooled down. Just like heating curves, cooling curves have horizontal flat parts where the state changes from gas to liquid, or from liquid to solid. These are mirror images of the heating curve.
