Storage and loss modulus

The storage modulus (G`) measures the energy which is stored in the sample and which will be released after mechanical stress. On the contrary the loss modulus describes the viscose part of the sample, which is equivalent to the loss of energy which is transferred through friction into heat.

The diagram shows the storage and the loss modulus of a NBR compound. This evaluation serves a comparison between the elastic and the viscous material behaviour.

A GÖTTFERT Rubber RPA Visco Elastograph provides the opportunity to collect the described data. Such kind of data is particularly interesting for quality control as well as Research departments and institutes which are mainly focused on rubber.
