The DSR makes it possible for item developers to create toothpaste with the right uniformity so that it can be squeezed from a tube yet not drop off the toothbrush. The DSR tests binder put in between 2 parallel plates about the dimension of a quarter. One of home plates moves and the maker gauges the viscoelastic properties of the asphalt.
