Glass transition temperature ( \(T_\)) and the polymer transforms from the crystallisation to the melted, state. This data provides extremely valuable information on key physical and chemical properties associated with thermosetting materials, including: The heat flow is measured as a direct function of time or of the sample temperature. This is done by integrating the peak corresponding to a given transition. This curve can be used to calculate enthalpies of transitions. There are two different conventions: exothermic reactions in the sample shown with a positive or negative peak, depending on the kind of technology used in the experiment. The result of a DSC experiment is a curve of heat flux versus temperature or versus time. The reference sample should have a well-defined heat capacity over the range of temperatures to be scanned. Generally, the temperature program for a DSC analysis is designed such that the sample holder temperature increases linearly as a function of time. Both the sample and reference are maintained at nearly the same temperature throughout the experiment. Differential Scanning Calorimetry (DSC) is a thermo-analytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. ![]()
