Determining the glass transition temperature in the laboratory
You want to determine the glass transition temperature of your materials
What is the glass transition of a material?
The glass transition temperature (Tg) is an important parameter in materials science. It is the temperature at which a material such as a polymer or glass changes from a rigid, brittle state to a soft, rubbery state.
Why determine the glass transition of a material?
The glass transition temperature of a material is an important parameter to take into account:
when designing polymer and glass materials: the Tg affects their mechanical properties and resistance at different temperatures. Determining the glass transition temperature enables manufacturers to choose the right material for a specific application.
to develop R&D materials
to assess a material's thermal stability. A material with a high Tg will be more resistant to high temperatures.
for understanding the mechanical properties of a material. By determining the Tg, we can find out how a material will behave when subjected to mechanical loads at different temperatures.
for quality control: manufacturers can ensure that their products meet the required specifications by measuring Tg.
The FILAB laboratory carries out analyses to determine glass transition
The FILAB laboratory carries out glass transition analysis using thedifferential thermal analysis (DTA) method. This analysis technique is used to measure the temperature variation between the sample under study and a reference during an exo- or endothermic reaction. This allows us to study phase transitions and diagrams and the glass transition, among other things.
DSC calorimetric analysis(DSC analysis) can also be used to determine the phase transitions of a material:
