Thermo mechanical Analysis
Thermo mechanical Analysis (TMA)
Thermomechanical Analysis (TMA) is a powerful analytical technique used to study the dimensional changes and mechanical properties of materials as a function of temperature and applied force. It is particularly useful for characterizing polymers, composites, and other viscoelastic materials. TMA provides valuable insights into various material properties, such as glass transition temperature, coefficient of thermal expansion, softening behavior, and dimensional stability.
TMA operates by applying a controlled force to a sample while subjecting it to a temperature program. The linear dimensional change (expansion or contraction) of the sample is measured as the temperature and/or applied force is varied. The measurement is typically performed using a sensitive probe that detects the sample’s dimensional changes. The resulting data is plotted as a curve of dimension change versus temperature or force, revealing important transitions and behavior of the material.

Sample dimensions: Bulk samples typically have a height/thickness range of 0.5 mm to 26 mm and a width/length range of 5 mm to 10 mm. Film/fiber samples should have a maximum uniform thickness of 1 mm.
Sample geometry: Bulk samples should have reasonably flat and parallel faces for expansion/contraction measurements. Films or fibers are suitable for tension force measurements.
