Product Description
Thermomechanical Analysis (TMA)
Precise Determination of Coefficients of Thermal Expansion (CTEs) and Transitions
The TMA/SDTA 2+ can be used for a wide range of applications due to its broad temperature range and the wide choice of force parameters in compression and tension modes. As a result, the TMA/SDTA 2+ quickly provides characteristic information on numerous types of samples, for example very thin layers, large sample cylinders, fine fibers, films, plates, soft or hard polymers, and single crystals.
Thermo mechanical analysis (TMA) is the ideal addition to DSC. Besides the measurement of expansion coefficients, TMA is also an excellent technique for determining glass transitions that cannot be satisfactorily measured by DSC, for example materials with a high filler content. The penetration mode is ideal for characterizing the glass transitions of difficult samples such as very thin coatings.
FAQ
