Overview

Dynamic mechanical analysis (DMA) is used to measure the mechanical and viscoelastic properties of a material as a function of temperature, time and frequency while it is subjected to an oscillating stress.

DMA is an important technique used to measure the mechanical and viscoelastic properties of materials such as thermoplastics, thermosets, elastomers, ceramics and metals.

In DMA, the sample is subjected to a periodic stress in one of several different modes of deformation (bending, tension, shear and compression).

Modulus as a function of time or temperature is measured and provides information on phase transitions.

DMA technology is the perfect solution when maximum accuracy is required and the material has to be characterized over a wide range of stiffness and/or frequency. In addition, DMA technology is extremely versatile and therefore, DMA can characterize materials even in liquids or at specific relative humidity levels.

The METTLER TOLEDO DMA/SDTA1+ sets new standards in the market. In comparison with conventional DMA instruments it offers new and unique performance benefits:
A frequency range up to 1000 Hz for material behavior simulation and accurate determination of moduli through the presence of a dedicated force sensor.

Unique measurement of both displacement and force results in a very accurate determination of moduli
Wide force range from 1 mN to 40 N allows you to measure very soft and very stiff samples
Broad frequency range from 0.001 to 1000 Hz means you can perform measurements under real conditions or more rapidly at higher frequencies
