Instrument description
MV 3000 Basic
Entry level Mooney Viscometer
The MV 3000 Basic is a rotational shear viscometer according to Mooney for performing
– Viscosity tests (ML / MS 1+X)
– Stress Relaxation testing
– Mooney Scorch
– Delta Mooney testingon polymers as well as rubber compounds for quality control, research and development applications.
The MV 3000 Basic is supplied as a complete, ready-to-test instrument set including a personal computer, MonControl Software, cables, connectors and regulators as well as a standard set of tools and consumables.
Easy to use:
All test parameters are pre-programmed through the MonControl Software – the instrument is equipped with a single button for starting the test sequence.Direct feedback:
An integrated multi-color LED status bar clearly displays the current machine state.Rugged:
The compact and highly rigid frame is made from high strength aluminum. Along with direct-drive technology, this guarantees stable and accurate test results in every environment.Rotor, die assembly and drive system
The most fundamental and important parts on a Mooney Viscometer are the rotor, die assembly and in-line drive shaft. The test sample is placed below and above the rotor with optional test film. Then the upper die is lowered onto the lower die with a force of 11.5 kN.
After a pre-heat time, the rotor – which is now totally embedded in the test material in the closed die cavity – rotates at a fixed speed of 2 turns per minute, powered by an in-line drive system.
During the whole test sequence, the temperatures of both dies are measured by a separate precision probe on each die and the heaters are accordingly controlled and regulated to precisely maintain the temperature at its setpoint.
The torque needed to turn the rotor in the test material is precisely measured by an in-line torque transducer. Torque in Mooney Units (MU), die temperatures and rotor speed are recorded. Data is automatically calculated and displayed once the test is completed.

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.
