Our established Mooneyline Viscometer is the perfect choice for all professionals, suited for the modern laboratories at all stages of the rubber production process, efficiently producing accurate data on a variety of elastomeric compounds.


The rotor and die assembly of our Mooney Viscometer are fundamental for producing a controlled test environment of heat and pressure at a constant rotor speed. A sample of test material is placed above and below the rotor and the platens then closed under pressure. By the means of microprocessor based PID control system, the temperature of the dies and sample contained are accurately maintained.

The rotor rotates at a constant speed to two revolutions per minute (2 RPM) and by means of a precise transducer system located below the die assembly, the torque exerted on the rotor head is measured and recorded within the system data files.


The Mooneyline Viscometer has the ability to be programmed for measuring the Stress Relaxation index of material samples. This feature enables the user to measure the decay of viscosity by firmly locking the rotor after the programmed test time has elapsed.

In addition to this the equipment conforms to international standards and meets the requirements of ASTM D1646 performing industry standard tests on a wide range of compounds prior to manufacturing processes, such as:

  • ML (1+X)
  • Scorch
  • Delta Mooney

Mooneyline VSC


It is strongly recommended that samples are prepared with an automatic Volumetric Sample Cutter.


Our Mooneyline VSC provides reliable and consistent sample preparation of shape, size and volume. An additional benefit of this type of cutter is during the cutting process a hole is punched in the middle, ready to accept the rotor.
