Mooney Viscometer

It is an instrument consisting of a motor driven disk within a die cavity formed by two dies maintained at specified conditions of temperature and die closure force. It measures the effect of temperature and time on viscosity of rubber or compound.It is a measure of the viscosity of a rubber or compound determined in a Mooney shearing disk viscometer. It is indicated by the torque required to rotate the disk embedded in a rubbercompound specimen and enclosed in the die cavity under specified conditions.Deviation in viscosity of the compound will critically alter its processibility specially in terms of calendering, extruding or injection moulding. It is necessary that viscosity parameter be maintained within specified limits. To do this Mooney Viscometer is of vital importance. In fact viscometer has manifold advantages.
