DSC anaysis
The GWP Plastics Laboratory offers DSC analysis for plastics analysis among other methods. Differential Scanning Calorymetry (DSC) is one of the most frequently used methods of thermal analysis due to its versatility and the high significance of the results.
Application of Differential Scanning Calorymetry
DSC analysis can be used to investigate a wide range of materials such as polymers, resins, composites or other organic materials. Heat flow differences between a sample and a reference sample are measured during a controlled temperature-time programme. Valuable information for research and quality control of polymers can be obtained from these data.
Typical applications of DSC include, for example, the investigation of morphological structures, the differentiation of plastic types, the detection of batch differences in moulding compounds, the investigation of the influence of processing conditions on material quality, effects of additives, ageing influences, decomposition effects, damage analyses and purity determinations.
How DSC analysis works
In dynamic differential calorimetry, the amount of heat released or absorbed by a sample is determined during constant heating or cooling. In an encapsulated crucible a) the sample to be analysed and in a second crucible b) a reference (empty crucible) are heated and then cooled.
During temperature control, exothermic or endothermic processes or phase changes such as melting or evaporation occur in the sample. The temperature changes ΔT compared to the empty sample (reference) are determined and can be assigned to a material via databases.
