For instance, here the DSR enables product developers to develop tooth paste with the right consistency to ensure that it can be pressed from a tube but not diminish the toothbrush. The DSR tests binder put in between 2 identical plates regarding the dimension of a quarter. One of home plates steps and the maker determines the viscoelastic properties of the asphalt.
