Tg - Glass Transition Temperature for Epoxies
... As discussed previously, Tg is actually a temperature range, rather than a specific temperature. The convention, however, is to report a single temperature defined as the midpoint of the temperature range, bounded by the tangents to the two flat regions of the heat flow curve. For the epoxy material ...
