Instrument description
MV 3000
Industry standard Mooney Viscometer
The Mooney Viscometer MV 3000 is the leading test instrument for measurement of viscosity, scorching and stress relaxation on polymers and rubber compounds.
The MV 3000 is suitable for quality control as well as research and development purposes with excellent repeatability and reproducibility due to its low-mass die design, direct heating and a unique direct drive design with snap-in mechanics.
The massive aluminium frame of the MV 3000 with its 270° accessible die area allows easy sample loading while integrated rotor ejection simplifies rotor handling. Operation is made easy by 4 illuminated pushbuttons providing clear information about the machine state. A motorized safety shield separates the die area before the test sequence is started.
Die temperatures are accurately and precisely measured by calibrated probes and controlled with a precision of +/- 0.03 °C by heaters, dies and rotors with an extremely fast thermal response.
The MV 3000 is fitted with built-in software-controlled systems for automatic balancing and calibration, including a double dead-weight system to apply a defined torque of 100 Mooney units, ensuring the utmost data accuracy and eliminating the needs of any external tools or fixtures.

Applications
Mooney Viscosity
The Mooney Viscosity test is the most popular test method for characterizing polymers and uncured rubber materials. As defined by international standards, the sample material is preheated for a defined period in a closed die cavity, then sheared by the embedded rotor at a constant rate. The 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 making it easy to differentiate between different types and grades of polymers in order to ensure a high processing consistency.
Mooney Stress Relaxation
As Mooney Viscosity testing only provides information about the flow = viscosity of polymers and rubber compounds, stress relaxation testing can be used to assess elastic material behavior. This does not even require additional samples or testing efforts. Once the Mooney Viscosity test is completed, the rotor is stopped within 5 milliseconds and the torque decay is observed and recorded. Once the stress relaxation is completed, the slope-intercept and regression coefficient are calculated, providing excellent correlations in reference to polymer branching and processing.
Mooney Scorch
Mooney Scorch is one of the most useful tests to determine starting of cure - so called scorching behavior - of rubber compounds, providing essential data for designing and controlling production processes as well as checking material consistency. Of course, every MonTech Mooney Viscometer offers full Mooney Scorch and Delta Mooney testing capabilities featuring a selection of over 3500 datapoints which include initial Mooney viscosity, minimum viscosity, scorch times and scorch viscosities.
Mooney Viscosity at Shear Rates and Temperatures
Besides only static testing, MonTech Variable Mooney Viscometers such as the V-MV 3000 offer full dynamic testing capabilities, allowing measurement of viscosity at variable shear rates (by stepless changes of the rotor speed) and temperatures. Furthermore, even non-isothermal sequences, variable rotor speed profiles as well as step-relaxations can easily be programmed and executed. Overall, this allows a detailed and complete understanding of the polymer behavior. Along with this, low rotor speed rates in Mooney Viscosity testing even provide the ability to test highly elastic and shear sensitive materials that could not be properly tested and characterized on Mooney Viscometers before.
