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.
