Thermomechanical Analysis (TMA)

Precise Determination of Coefficients of Thermal Expansion (CTEs) and Transitions

METTLER TOLEDO’s TMA/SDTA 2+  instruments  can be used for a wide range of applications due to the broad temperature range and the wide choice of force parameters in compression and tension modes.

• Accurate and precise determination of thermal expansion co-efficients.
• Nanometer resolution from -150 to 1600ºC.
• Provides quick characteristic information on numerous types of samples, such as very thin layers, large sample cylinders, fine fibers, films, plates, soft or hard polymers and single crystals.
• 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.
• SDTA signal ensures temperature accuracy of sample in all operating modes.
• This enables temperature adjustment to be carried out using reference substances (the melting points of pure metals) or through a change in length.
