The Mooney viscometer consists of a rotor rotating (@2 rpm) in a closed heated cavity chamber filled with uncured rubber.A shearing action develops between the compound and the rotor, and the resulting torque (resistance of the rubber to the turning rotor) is measured in arbitrary units called Mooney units, which directly relate to torque. The larger the number, the higher the . Mooney Viscosity. This test is the most commonly used test method for characterizing uncured rubber materials and polymers. The sample material is heated for a predetermined period of time, then sheared by an embedded rotor at a constant rate. We then record the Mooney Viscosity and automatically calculate data at defined times and viscosity .Mooney viscometer The sample cavity of the Mooney vis-cometer is shown in Fig. 1. The rotor is embedded in a sample and the torque required to move the rotor at 2 rpm is measured. A typical Mooney viscosity measurement is the ML1+42. This test uses a 1 minute preheat with the motor off and then 4 minutes with the motor on at 2 rpm.
literature (Sherman, 1983) is the Mooney's equation (1951). Using functional analysis, Mooney derived the following equation to describe the relative viscosity/concentration behavior of rigid, spherical particles: T/, =exp[2.54>/(I-aM4>)) (1) where T/, is the relative viscosity, 4> is the volume fraction of the solids, and aM isThe Mooney Viscosity is recorded and data is automatically calculated at predefined time and viscosity points. MonTech Mooney Viscometers offer superior precision and repeatability, providing the user with reliable data and .Mooney Viscosity - Free download as PDF File (.pdf), Text File (.txt) or read online for free. Mooney Viscosity
The Mooney viscosity of the sample set was measured by the standard method and the values were in the range 65–95 units. The samples were divided in two subsets, one for calibration, containing 70 samples, and the other for external validation, containing the remaining 30 samples. The Mooney viscosity average values and their standard .
Generally speaking, this type of equipment, its operation and the interpretation of the results are too complicated to be used as a standard quality control tool at present. . On Mooney viscosity and Mooney stress relaxation I. J. Appl. Polym. Sci. 1999, 74 pp. 1207–1219 [5]
and the determination of its Mooney viscosity. If Mooney viscosity can be determined immediately after rubber refining, it will be critical for optimizing the process flow. As a result, Mooney viscosity prediction becomes a worthwhile subject of study. Mooney viscosity forecasting can be considered as a type of multivariate time series

This testing procedure strictly adheres to the standards outlined by ASTM D 1646, ISO 289-1, ISO 289-2, and ISO 289-3 .
To that end, we investigated Mooney torque relaxation. The Mooney viscometer is an inexpensive instrument (cost and maintenance) that is easy to use and, above all, available in the great majority of factories producing natural rubber. The measurement of NR Mooney viscosity is governed by international standard ISO 289. It is interesting that the Mooney viscosity for one of the `bad' lots was very close to the Mooney viscosity for the `good' lot (ML1+4 of 93 vs 94). Table 11 gives a description of these three lots. Fig. 31 shows very good separation of the `good' vs the `bad' lots of natural rubber when comparing the uncured tan δ at high strain test conditions.
