Viscosimetro Mooney MV 3000 Basic

VISCOSIMETRO MOONEY MV 3000 BASIC

Strumento entry level per prove di analisi viscosità, scottatura e stress relaxation nell'ambito del controllo qualità.

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 testing

on 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. 


 

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.
