Differential Scanning Calorimetry (DSC) Analysis/DSC差式扫描量热法

Differential Scanning Calorimetry, commonly known as DSC, is a thermo-analytical technique for polymeric and non-metallic materials. Most commonly used for detecting glass transition temperature and other thermal properties, differential scanning calorimetry is one of the most efficient and cost-effective polymer test methods available.

DSC testing has been used for decades as a way to predict the behaviors of polymeric materials under different thermal conditions. Like all calorimeters, this technique tracks the amount of energy required to increase the temperature of a material by a certain amount. By making accurate measurements of heat capacity and temperature, differential scanning calorimetry can detect changes in material properties at exact temperatures, revealing important transition ranges and deterioration points.

To perform DSC testing, a small amount of material is heated at a predetermined rate. The energy required to heat the sample is compared to an inert reference material at the same temperature. If the sample under test requires more energy compared to the reference, it is indicated as an endotherm. The peak of an endotherm indicated melting temperature. When less energy is required to heat the sample as compared to the inert reference, an exothermic peak is observed. This may indicate a chemical reaction such as curing is taking place.
