VR-7130 Automatic DMA was designed to eliminate possible causes of measurement errors and variability by adopting the full automatic system and the unique temperature sensor. In combination with THERMO JETTER, it can measure viscoelasticity down to -90°C without using liquid nitrogen.

A high-polymer material is a viscoelastic material, unlike elastic materials such as metals. In the case of elastic body, strain (response) comes up simultaneously to the given force (input). On the contrary, in case of a high polymer material, time lag will occur between input and response. These relations are different by the sample components and also dependent on temperature, velocity and strain. High polymer materials are used for various uses and regions by using such differences.
As these properties are mainly treated as material properties, response to very minute input (force or strain) will be mainly measured. (Strain is measured to force or force to strain.)
