The DSR makes it possible for product designers to create toothpaste with the right uniformity so that it can be pressed from a tube however not fall off the tooth brush. The DSR tests binder placed between 2 parallel plates regarding the dimension of a quarter. Among the plates relocations and the equipment gauges the viscoelastic buildings of the asphalt.
