Rotational Rheometer Anton Paar MCR301

Rotational rheometry is a technique for the measurement of material deformations and rheological properties, such as melt viscosity. During the measurement, the sample is subjected to shear deformation by constantly rotating or oscillating measuring system.

Measuring systems:

  • Plate/plate and cone/plate geometries for polymer melts

  • Concentric cylindrical geometry for liquids, suspensions and solutions

  • SER-extensional rheology system for polymer films

  • Sample holders for solid polymeric materials

  • Magneto-Rheological device for magnetorheological fluids

Technical details:

  • Maximum temperature depends on the measuring system

    • Plate/plate, cone/plate, SER and solid samplesRT-600ºC

    • Concentric cylindrical -20 to +200 °C

  • Maximum torsional moment 200 mNm

  • Frequency 10^-5-628 Hz

Capillary Rheometer Göttfert Rheograph 6000

Capillary rheometry can be used to study the rheological properties of molten plastics and elastomers at different temperatures. Rheolocigal properties are needed in mould and tool simulation of injection moulding and extrusion processes. Capillary rheometer is used to measure viscosity and shear stress at high shear rates, which provides valuable information about the material’s behaviour in actual process environments that can be used to solve material based problems in processing.

Advanced Polymer Analyzer (APA2000)

The Advanced Polymer Analyzer (APA2000) is used to study the dynamic mechanical rheological properties of rubbers and other polymers (before, during and after curing or melt solidification). Tests possibilities include cure tests, sweep tests and stress relaxation tests.

Operating conditions:

  • Torque 0-22.6 Nm

  • Frequency 0.0015-33.33 Hz

  • Strain 0.28-1256%

  • Temperature 30-230oC

  • Time 0.01-9999.99 min

Melt flow index tester

The melt flow is measured according to the ISO 1133 standard. In this method, the ease of flow of the melt (g/10min) is measured at a certain temperature at a certain loading. The test equipment includes a vertical heated cylinder, in which the sample is placed, a die in the bottom of the cylinder and a piston and weight above the sample. The sample is let to flow through the die with certain diameter and the mass of the flown polymer is measured.
