The most advanced Mooney Viscometer available

In today 's competitive environment, process control and product quality are of paramount importance. The rubber industry demands reduced viscosity variation in raw polymers and compounded materials and a better prediction of processing behavior, to achieve uniform processing, so eliminating lost time and scrap product due to off specification materials. The MV2000 has been developed to meet these exacting requirements and has become the worldwide industry standard.

The Mooney Viscometer has been used in the rubber industry for more than 50 years. The MV 2000 builds on that tradition providing the best available sample heating, precise torque measurement and on board microprocessor control.

In addition, stress relaxation can be measured at the end of the Mooney viscosity test, indicating both elastic and viscous properties of the sample.

The MV 2000 meets international and national standards for Mooney viscosity and scorch tests and is available with a comprehensive range of software packages.

• More repeatable and reproducible than other s
• Automatic balance and calibration at the press of a button
• Less test variation means greater sensitivity to rubber variations

Major features

Designed for precision

Management of temperature by software algorithm improves temperature stability and response. High quality torque transducer and reaction torque measurement eliminate drift.

Excellent scorch precision

The MV2000 's precise temperature response and improved temperature accuracy improves scorch test repeatability and reproducibility.

Improved test efficiency

The MV2000 's rapid temperature response aids changes in temperature set point thus improving testing efficiency.

Stress relaxation

The stress relaxation test is increasingly used worldwide to quantify the elastic behavior of polymers and compounds. Stress relaxation data provides information on compound mixing and processing properties. In addition stress relaxation is used as a polymer development tool and as a control on incoming polymers.

Designed for ease of use

• Printed calibration certificate

Operation

• Long rotor shaft for easy sample loading
• Set temperature and test time on digital display, auto load test conditions from data collection system
• Test runs automatically
• Optional auto open when test is completed

Reduced test cost

• Low maintenance
• Easy to change test conditions

Maintenance and cleaning

• Bayonet mount motor means easy, rapid rotor shaft cleaning
• Easy rotor height adjustment
• Sealed membrane keyboard
• Bearings run cooler for extended life
• Cross head design assures consistent die alignment
• Simpler design reduces component failures

Long life seal*

Typically provides ten fold increase in seal life, further reducing routine maintenance. Sealing the rotor cavity from the test material is often a problem. The normal 'O'-ring around the rotor shaft wears and allows material to enter the bearing housing mechanism. This necessitates cleaning and 'O'-ring replacement on a routine basis to maintain accurate test results.

Alpha Technologies has developed a unique long life seal. This composite seal typically has a working life of ten times that of the standard 'O'-ring seal, dramatically extending the period between seal replacement and cleaning. Accurate, precise test results are ensured with a tenfold reduction in maintenance time.
