Improved repeatability of DSC characterization of TPU by means of supportive use of heat-transfer agents

The characterization of materials by means of differential scanning calorimetry (DSC) may contain measurement artefacts originating from the undefined contact area between the material sample and the pan surface. Especially in cases where low thermal conducting materials are investigated, this conta...
