V-MV 3000 Variable Mooney Viscometer
The variable rotor speed Mooney Viscometer achieves more innovative Mooney values for greater R&D and production purposes.
The V-MV 3000 applies variable shear rates for a more advanced and complete characterization of molecular and processing properties of rubber specimens. This is made possible by the latest direct servo drive technology mounted in a high-strength industrial load frame. The superior design enables unbeaten data accuracy and test result precision.

View Applications
- Mooney Viscosity
The Mooney Viscosity test is the most popular test method for characterizing polymers and uncured rubber materials. 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
While Mooney Viscosity testing only provides information about the flow/viscosity of polymers and rubber compounds, stress relaxation testing assesses elastic material behavior.
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 tests determine onset of vulcanization (also known as scorching behavior) in rubber compounds. This provides essential data for designing/controlling production processes and verifying material consistency.
Every MonTech Mooney Viscometer offers full Mooney Scorch and Delta Mooney testing capabilities. These capabilities feature a comprehensive selection of data points such as initial Mooney viscosity, minimum viscosity, scorch times and scorch viscosities.
- Mooney Viscosity at Shear Rates and Temperatures
MonTech Variable Mooney Viscometers offer full dynamic testing capabilities, allowing measurement of viscosity at variable shear rates and temperatures matching process conditions.
Non-isothermal sequences, variable rotor speed profiles, and step-relaxations can easily be programmed and executed. This allows a detailed and complete understanding of the polymer behavior.

Pneumatic Cooling System
This pneumatic air cooling system cools both dies separately using independent PID-controllers, rapidly cooling the instrument from higher to lower testing temperatures. When using non-Isothermal and RPA operation modes this system enables cooling at any point during the test.
- • Allows test sequences to follow precise cooling ramps and steps
- • Conducts friction heat away from the sample when testing at high shear rates
- • Reduces non-productive time of the instrument and operator by shortening stabilization time
- • Air lines have quick connects at each platen, and exhaust through the platen assemblies
- • Air is supplied by an independent regulator on the back of the machine
Instrument Control Panel
The 5“ Color-Touchscreen allows the machine to be operated from a remote computer or completely standalone for simple quality control testing.
