MonTech Mooney Viscometer Application Examples

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. -
Cooling options
Pneumatic cooling system
Both test dies are cooled separately by a PID-controlled forced air cooling system.
This system can be used to rapidly cool the Viscometer from a higher testing temperature (e.g. testing Mooney Scorch at 160°C) to a lower testing temperature (e.g. Mooney Viscosity testing at 100°C), significantly reducing operator waiting and nonproductive times of the instrument.
On the V-MV 3000, this option can further be used for running Non-Isothermal testing sequences as well as actively cooling friction heat.
Reference polymers for Mooney Viscosity
Integrated cartridge cooling system that allows cooling of the test dies and rotor below room temperature down to +10°C, adding additional test capabilities especially for low viscosity materials such as silicones, latex and epoxy resins. This technology is worldwide patented by MonTech.
