The rotor’s torque curve graph as a function of time is a vulcanization curve or rheometric curve. Sponsored WHAT DOES THE RHEOMETRIC CURVE TELL US? WHAT ARE THE VALUES OF ML, MMH, TS2 and T’90? WebFirst, a compound at room temperature is inserted into a preheated cavity of the rheometer. As the compound heats up, its viscosity drops, which is reflected in a decreased torque (resistance) on the rotor. The lowest value of the torque curve, expressed in dN*m, is called ML (Moment Lowest). What is the viscosity determination method?
