Differential Scanning Calorimetry (DSC) is a technique used by labs to understand how polymers respond to heat. This material testing technique is highly preferred for its ability to deliver precise readings on the heat capacity of a specific material. We are a reliable differential scanning calorimetry testing lab and can help you unveil the difference in the amount of heat energy needed to increase the temperature of a particular sample.
There are various uses of DSC tests. They come in handy when observing glass transition and crystalline polymer melting. The tests could also be used to study oxidation, fusion, and various other chemical reactions. Typically, the analysis is required to study polymer curing, evaluate the purity of a sample, and generally ensure quality control amid polymer materials.
When analyzing a material using DSC tests, we pay special attention to the DSC curve. In layman terms, this is the visual representation of the test results. These curves usually show heat flux versus time or temperature. This will all depend on your needs, goals, and how you intend to use the end material.
DSC curves serve as vital tools for comparison and benchmarking as you develop a product, upgrade it, or simply ensure better quality control. During the tests, we use a computer and heat two pans in the measurement chamber. We then place the sample in one pan for cooling or heating.
During the tests, we measure the temperature of the sample from below and also take the readings for the empty control pan. It is possible to determine the heat flow by merely comparing these two readings. However, various other physical and analytical tests must take place.
The DSC curve will need to be studied in detail by our skilled technicians to determine crystallization temperatures, transition temperatures, melting temperatures, and other crucial factors related to the properties of your material. Our services can help you reach your product goals and ensure unmatched quality control.
