What is Torque Rheometer ?
Torque Rheometer is a kind of experimental instrument to know the rheological performance of polymer material processing by measuring the torque and temperature change of polymer material under the pinching effect produced by a pair of rotors rotating anisotropically. By recording the counter-torque produced by the material to the rotor during mixing as well as the change of temperature over time, it can study the dispersing performance, flow behaviour and structural change of the material in the process (cross-linking, thermal stability, etc.), and also provide experimental guidance for production quality control. It can also provide experimental guidance for production quality control.

Working Principle of Torque Rheometer
When the measured material is added to the mixing chamber, the material is subjected to the force exerted by two rotors with different rotational speeds and opposite steering directions. The torque module measures this reaction force through the torque sensor, and then through the processing of the computer software, it comes up with the rheological map of the change of the torque with time. The equipment can simultaneously measure the torque (temperature)-time curve of the material in the refining process, and explore the differences and characteristics of the microstructure, macroscopic morphology and processing performance of the material through the subtle changes of the curve.
Types of rheometer
Torque Rheometer
Torque rheometer is available in 55ml, 200ml and 300ml types, and is ideal for studying the flow, plasticisation, thermal and shear stability of materials. The rheometer provides a dynamic measurement method that is closer to actual processing, and allows for the determination of the rheological properties of the material continuously, accurately and reliably under conditions similar to those of actual processing.
Capillary rheometer
Capillary rheometer can determine the fluidity and curing speed of thermosetting materials, can draw the stress-strain curve of thermoplastic materials, plasticisation curve, determination of softening point, melting point, flow point temperature. It can determine the viscosity and viscous flow activation of polymer melt, and also study the process conditions of melt spinning.

Frequently Asked Questions
What does a rheometer do?
+
-
A rheometer is an instrument that measures how matter flows in response to applied forces and quantifies its rheological properties. An extensional rheometer applies extensional stress or strain, while a rotational rheometer controls and applies shear stress or strain.
What is the application of a rheometer?
+
-
Thermal and Shear Stability Testing of Thermoplastic Materials by Rheometer.
What are rheological materials?
+
-
Generally, a rheological material is a material which can change is physical state very quickly.
Factors to Consider When Choosing a Rheometer or Viscometer?
+
-
1)Material Type and Properties.
2)Measurement Range and Accuracy.
3)Temperature Control.
4)Ease of Use and Maintenance.
What is a rheometer used for?
+
-
A rheometer is a laboratory device used to measure the way in which a viscous fluid (a liquid, suspension or slurry) flows in response to applied forces.
