The SMV-301 / 301RT allows the user to measure the Mooney viscosity, scorch time, minimum Mooney viscosity, and other characteristics of rubber in accordance with JIS, ISO, and ASTM test methods. With outstanding temperature recovery characteristics and easy operability, it can also be used for stress relaxation measurements or for tests that .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 is
Mooney viscometers are mainly used to test characteristics of raw materials before mixing - to verify that they meet required standards for the formulation in which they are to be used. To perform a Mooney Viscosity Test, the die cavity temperature is set and allowed to stabilize. Then, a specified volume of the sample material is loadedA Mooney viscometer MV 2000 Mooney Viscometer.

The standardized Mooney viscosity, though used to characterize viscoelasticity in elastomers, often exhibits unsatisfactory discriminatory power since it does not distinguish between the measure .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]Mooney viscosity ML (1+4) 100°C was obtained. The Mooney viscosity is therefore value of torque (in MU) 5 min from the test beginning. After stopping of rotor (at this 5 min time) the stress relaxation of rubber sample (i.e. decrease of torque values in MU) was measured for next 3 min. Fig. (1). Mooney viscosity and Mooney relaxation for .The Mooney Viscosity of Raw Natural Rubber G.M. BRISTOW* Non-standard Mooney test parameters have been derived for a range of raw natural rubber grades in an attempt to obtain information other than a simple assessment of viscosity. Increasing the pre-heat time to 5 tnin and observing the torque-time relation over 1-4 min
Traditional data-driven empirical models for online prediction of the Mooney viscosity have not utilized the information hidden in lots of unlabeled data (e.g., process input variables during each mixing batch). A simple semi-supervised nonlinear soft sensor method for the Mooney viscosity prediction is developed. 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.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.
