Webresults. There are, however, some common DSC events/ transitions that can be the cause of less than optimum results and/or misinterpretation. This paper describes several of these events with causes and solutions. Figure 1 is an artificial DSC curve which was generated to illustrate these events/transitions. The curve is artificial in Webthe glass transition by DSC. Analysis of the glass transition can be important for checking the operating range of a material in which the mechanical strength is retained, defining a …
WebIn more than 300 DTA/DSC studies of Tg published over a period of 2005-2006 the authors specified the way of Tg determinations only in 68 publications. 70% of these authors used point A, 20% point B and 10% point C. In about 250 papers (out of 300) the way of Tg determination was not specified. At the same time, as is seen from the caption to ...

At temperatures well below the Tg (e.g., Tg – 40 °C), aging occurs much more slowly. If the experiment were performed with an aging temperature of 100 °C, the aging process would be so slow that very little difference would be seen in the samples after just five days.
WebThis allows the degree of cure (DOC) to be measured through differential scanning calorimetry (DSC) characterization of resin samples and is modelled as follows x = ∫t1t0hdt HR. Where, x = Degree of cure. HR = Heat of reaction - total [J/g] h = Specific heat flow [W/g] Visually, from a DSC characterization of the specific heat flow curve ...
