Brand

TA Instruments Q800

Temperature range

-140 to 600 °C

Frequency range

0.01 – 200 Hz

Maximum force

18 N

Modes

Dual / single cantilever
3-point bending
Film-tension
Compression

Output

Viscoelastic behavior of materials

Coefficient of Thermal Expansion (CTE)

DMTA is a technique used to analyze the viscoelastic behavior of a material as a function of temperature of frequency. From the resulting variation in material stiffness, properties such as the glass transition temperature (Tg) can be determined. Transitions corresponding to other molecular motions can be identified as well.
