TMA measures thermal expansion and effects such as softening, crystallization and solid-solid transitions, which provide insight into the composition of materials and hence their possible applications.
TMA offers the following measurement modes, which permit the analysis of diverse samples:
- Dilatometry
- Penetration
- Tension
- 3-Pt bending
- Swelling
- Volumetric expansion
This tutorial video shows TMA sample preparation for the above measurement modes. For dilatometric and penetration modes we use a PET sample. A punched out piece of transparency film and a thin textile is used for tension mode. We also demonstrate the use of the three-point bending device on a bar of printed circuit board. In the swelling tool we prepare a piece of a gummi bear in water, and finally, for volume expansion mode we use an oil sample.
