As an example, the DSR makes it possible for product developers to create tooth paste with the appropriate uniformity to ensure that it can be squeezed from a tube but not diminish the toothbrush. The DSR tests binder positioned in between two identical plates concerning the dimension of a quarter. Among the plates moves and the machine measures the viscoelastic buildings of the asphalt.
