Mooney Viscometer |
|
| Features |
Mooney Viscometer is a shearing disk Viscometer, designed for accurate measurement of viscosity, 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 confined in a heated die cavity maintained at specified temperature and kept closed by a specified force. As the disk rotates its experiences a shear strain. This resistance to rotation 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. An 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: |
- Method of sample preparation
- Mooney viscosity number
- Rotor size
- Preheat time
- Time interval to viscosity reading
- Temperature of test
|
| |
| Typical test results are stated as under: 50ML(l+4)100C |
| Where, |
- 50M = Viscosity in mooney units
- L = Large rotor (for small replace it with 'S')
- l =Preheat time in minutes
- 4 = Time in minutes after starting the motor at which the reading is taken
- 100C = Test temperature
