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.Different rubber compounds may exhibit varying Mooney Viscosity values based on factors such as the type of rubber, the presence of additives, and the degree of vulcanization. The test is particularly useful for comparing different formulations and optimizing rubber processing parameters to achieve desired properties and performance in 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 .AN ATTEMPT FOR CORRELATION BETWEEN MOONEY VISCOSITY AND RHEOLOGICAL PROPERTIES OF FILLED RUBBER COMPOUNDS D.

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.

Mooney viscosity is an important indicator of the performance and quality of the compound [2], [3]. . The experimental samples were selected from seven different Mooney viscosities of a certain type of rubber (Mooney viscosities of 64.8, 66, 67, 67.9, 69.2, 69.9, and 71, respectively), and 80 sets of data were collected for each set of Mooney . The influence of mixed rubber processing technology on Mooney viscosity and burning time was studied. The results showed that the Mooney viscosity of mixed rubber increased with the extension of .
