DSC thermal analysis is a great way to study a polymer’s response to heat. It is also available for a wide range of other samples, such as elastomers and plastics, serving a wide range of industries. DSC analysis measures the amount of energy absorbed or released by a sample when it is heated or cooled, providing data on heat absorption and heat evolution processes.

Two pans are loaded into a chamber – one with the sample loaded, and the other is empty (for reference). While the chamber is heated at a constant rate, the pans are monitored for heat flow. The output of this test is a curve which shows the polymer’s glass transition temperature, crystallization temperature and melting temperature. This curve can then be compared to a catalog of reference curves to identify its composition. If materials are blended together, the delta H under each of the melt transition peaks can be used to approximate the percentage of each.

DSC thermal analysis is used to determine the thermal properties of plastics, adhesives, foods, lubricants, oils, catalysts and much more.
