NETZSCH Température Modulated DSC Température Modulated Differential Scanning Calorimetry (TM-DSC) is a DSC technique whereby a sample is subjected to a superposition of a linear and a periodic temperature program. With the temperature modulated DSC method it is possible to separate overlapped DSC effects by calculating the reversing and the non-reversing signals. Glass transitions can therefore be well separated from e.g. curing, decomposition, evaporation, relaxation or cold-crystallization processes. The following figure shows the curing of an unsaturated polyester resin and how the overlapping of an endothermal glass transition can be separated from exothermal curing in a single TM-DSC test.
