Mooney Viscometer

Mooney Viscometer is a shearing disk viscometer, designed for accurate measurement of viscocity, scorch time and cure rates of the elastomers.

The instrument consists of flat, cylindrical disk, driven by a motor to rotate slowly and continuously in one direction. This disk is embedded into elastomer specimen which is confiend in a heated die cavity maintained at specified temprature and kept closed by a specified force. As the disk rotates its experiences a shear strain. This resistance to rotates offered by the elastomer is shearing viscosity which is proportional to mean absolute viscosity of the specimen.

Normally a preheat period is given to the elastomer following which the disk starts to rotate. A initial high viscosity is recorded and then as the viscosity also decreases, to a minimum value Viscosity obtained with large rotor are approximately twice those of small rotor.


The viscosity is reported as under:

1. Method of sample preparation
2. Mooney viscosity number
3. Rotor size
4. Preheat time
5. Time interval to viscosity reading
6. Tamperature of test

Typical test results are started as under

= 50ML(I+4) 100C


50M = Viscocity in mooney units.
L = Large rotor (for small replace it with S).
I = Preheat time in minutes.
4 = Time in minute after starting the motor at which the reading is taken
100 C = Test temprature
