- Interactive Q&A
The glass transition is the transformation of a substance from a glassy to a rubbery state, or vice versa. Knowing the temperature at which this transformation occurs is critical for understanding a material’s properties and behavior and how it can be used.
Thermal analysis offers several ways to determine the glass transition temperature (Tg): differential scanning calorimetry (DSC), thermomechanical analysis (TMA), and dynamic mechanical analysis (DMA).
Join our webinar to discover the effectiveness of these techniques using a variety of application examples.
Why is knowledge of the glass transition so important?
The glass transition provides information about the molecular properties of a material as it is heated or cooled within a certain range. It defines the upper temperature limit for the use of solid amorphous materials, and the lower temperature limit for rubbery materials. It can also provide information about the degree of cure.
Knowing the glass transition is important for optimizing production parameters and material properties. In addition, the Tg can be used to identify and compare materials and is therefore important in quality control and in failure analysis.
Join the webinar to expand your knowledge and improve your understanding of this critical property. Don’t forget to have your questions ready for our experts!
