As an example, the DSR makes it possible for item developers to produce toothpaste with the right uniformity to make sure that it can be pressed from a tube however not diminish the toothbrush. The DSR examinations binder put in between 2 identical plates about the dimension of a quarter. Among the plates actions and the machine determines the viscoelastic properties of the asphalt.
