Using Different Thermal Analysis Techniques to Measure Glass Transition

Glass transitions occur in all non-crystalline or semicrystalline materials and lead to significant changes in material properties such as thermal expansion, specific heat capacity, or modulus. This webinar discusses how to use thermal analysis to characterize glass transitions.

Date: February 4, 2022
Time: 10 AM EST (7 AM PST / 4:00 PM CET)
Duration: 1 hour
Presented by:


The basic requirement for a glass transition is a sufficiently large degree of molecular disorder, at least in one direction. During the glass transition, the material changes from the elastic to the viscoelastic state. The glass transition is influenced by the degree of crystallinity, crosslinking, plasticizers, blends, and fillers.

The webinar covers the basic theory of the glass transition and related thermal analysis techniques and methods such as DSC, TMA and DMA. Attendees will learn about relevant industry applications as well as practical applications of these techniques.

Key Takeaways

  • Understand the basic theory of the glass transition
  • Learn the advantages of the 3 main TA techniques, DSC, TMA and DMA, to measure the glass transition
  • Get the information in which industry glass transition temperatures can be of interest


Teresa Dennenwaldt, Applications Chemist, Thermal Analysis, Mettler-Toledo

Dr. Teresa Dennenwaldt obtained her PhD in chemistry in 2013. During her dissertation at the Institute of Physical Chemistry, Ludwig Maximilian University (LMU) in Munich, Germany, she specialized in the investigation of novel oxide- and nitride-based nanostructured materials by transmission electron microscopy (TEM) and its analytical techniques.

After successfully completing her PhD, she joined the Max Planck Institute for Iron Research (MPIE) in Düsseldorf, Germany for one year and the Ecole Polytechnique Fédérale de Lausanne (EPFL), Switzerland for three years as a postdoc in the field of electron microscopy and spectroscopy. In 2018, she joined Mettler-Toledo AG and has worked there ever since as an application specialist for Thermal Analysis. In her current position, she uses, teaches and supports DSC, TGA, TMA and DMA instruments at the METTLER TOLEDO AG head office in Switzerland.
