Mooneyline MV Variable Speed

Our most advanced Viscometer, complete with an adjustable rotor, can deliver variable speeds from 0.1 to 20 revolutions per minute (RPM). Thus facilitating extra functionality and producing accurate data on a variety of elastomeric compounds, making this an impeccable choice for polymer specialists.

Fundamental is the rotor and die assembly, with the test material placed above and below the rotor, held in place by pressure controlled platens. The temperature of the dies and the sample contained within are accurately maintained throughout the test by means of microprocessor based PID control system. The rotor speed of rotation can be varied from 0.1 to 20 RPM thereby enhancing the range of data that can be calculated during the test. This is a particularly useful function for testing of tyre compounds and polymers.

The Mooneyline Viscometer VS can perform a wide range of advanced tests to regulate the viscosity of polymer samples at varied speeds and temperatures. Along with industry standard tests in accordance of ASTM D1646 on a number of compounds prior to manufacturing processes including;

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

The measurement of Stress Relaxation index of material samples is one important feature that can be achieved with this sophisticated viscometer.

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.
