The DSR allows product programmers to create tooth paste with the best uniformity so that it can be pressed from a tube however not fall off the tooth brush. The DSR examinations binder put between 2 parallel plates concerning the dimension of a quarter. One of home plates moves and the maker gauges the viscoelastic residential properties of the asphalt.
