Thermomechanical Analyzer (TMA)/Analysis

Thermal expansion with neglectible load

Certain materials exhibit changes in their thermomechanical properties as they undergo temperature fluctuations. Understanding how materials expand or contract due to temperature shifts is crucial for manufacturers striving to deliver durable and reliable products. Linseis offers cutting-edge thermomechanical analyzers, designed for laboratory use, to precisely measure these physical transformations across a wide range of materials. Our thermomechanical services provide users with dependable measurements to guide their product development process. These instruments find applications in research and development, as well as quality control. Materials often subjected to such testing include plastics, metals, glass, and composites.

For expansion measurements using a thermomechanical analyzer (TMA), a probe gently rests on the sample while a stage exerts minimal downward pressure. Additionally, TMA facilitates various constant force experiments, including the measurement of penetration, bending, tension, shrinkage, swelling, and creep (evaluating sample movement over time under an applied load).

The TMA Platinum Series features a robust and dependable furnace, custom-designed to ensure rapid heating and cooling, as well as precise heating rate control across the entire temperature range.

The centrally located chamber is easily accessible and allows precise control of temperature and atmosphere. An optional mass flow controller is available for managing purge gas. The gas-tight cell can be evacuated, permitting measurements in a controlled atmosphere. Only such a system can provide definitive information on a sample’s susceptibility to oxidation.

All TMA devices adhere to various national and international standards, including DIN 51005, ASTM D 3386, ASTM E 831, ASTM D 696, and ISO 11359 – Parts 1 to 3, ensuring consistent and reliable results.

Cryo Option for Temperatures down to 10 K

LINSEIS “Ultra Low Temperature” series operates in a vertical (Zero-Friction) mode, providing an extensive temperature range from -263°C up to +220°C. This versatile series offers a wide array of sample holders, accommodates vacuum or controlled oxidizing/reducing atmospheres, and maintains the highest standards of accuracy and user-friendliness.

Expansion and Temperature Sensor

Every dimensional change in the sample is meticulously transmitted through the pushrod to a highly precise inductive transducer (LVDT sensor). This sensor offers consistent and reliable responsiveness throughout the entire temperature range, ensuring the highest level of reproducibility in TMA results. The temperature sensor, positioned alongside the sample, further enhances measurement accuracy.

In Dynamic Thermomechanical Analysis (DTMA), a sinusoidal stress, and linear temperature ramp are applied to the sample. This method measures the resulting sinusoidal strain, enabling the study of a material’s viscoelastic behavior. In D-TMA, the force exerted on the probe automatically alternates at the specified frequency.
