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.)
The VR-7130 has minimized possibility of human errors and realized excellent precision in viscoelasticity measurement of high-polymer materials.
