MOONEY-VISKOSIMETER 91.11

A shearing disk viskosimeter with a closed chamber and rotor.
The new developed device is used to determine the Mooney Viscosity and the scorch characteristics recorded over time. Typical test materials are unvulcanised rubber compounds and samples of pure natural or synthetic rubber. The functionality is especially simplified due to the new design.
The sample (consisting of two round blanks) is being sheared in the closed chamber by a constant turning rotor. During this procedure the resulting torque is recorded while pressure, temperature and speed are constant. 

Key Features:

• Table top instrument with latest control electronic for raw value recording and test data processing
• High sensible and precise torque transducer up to 200 ME
• According to ISO 289 1-4, DIN 53523 1-4 and ASTM D1646
• Measure procedures:
• Mooney Viscosity
• Mooney Scorch
• Mooney Relaxation
• Delta Mooney
• Temperature range up to 200°C
• Rotor drive with precise stepper motor and standard speed of 2 rpm
• Database Software „RubberView“ for parameter settings and measure procedure as well as free definable evaluation
• Universal handling with one multi function button, operating status is indicated by color of the button
• Compact, service friendly design with easily accessible components ready for remote maintenance
• Pneumatic rotor ejection

 

Further optional features:

• Rotor detection
• Air-/ Fluid tempering

Free definable constant speed from 0.1 to 5 rpm

Melt Tension Measurement, Haul-Off

The Haul-Off system measures the extensional properties of polymer melts by drawing a vertical melt strand at a constant pull-off speed or with a linear or exponentially accelerating velocity. The Haul-Off system measures the force needed to elongate the strand, and calculates elongation stress, draw ratio and apparent elongation rate and viscosity.
 The instrument is best used in combination with a suitable high pressure capillary rheometer (e.g. Rheograph 25, 75 or 120) where the device can be located close to the exit of the capillary. It may also be used with an Extrusiometer using a 90° deflection head (or exit) die.

Key Features:

• Freely selectable speed up to 8000 mm/sec, in the design „High Speed" up to 33333 mm/sec
• Freely selectable acceleration, either in linear or in exponential mode
• Anti-adhesion surface coated pull-off wheels
• Measuring range up to 2 N, resolution 0,001 N
