DW5300 Torque rheometer is a multi-functional, combined rheometer, which can study the dispersion properties, flow behavior and structural changes (crosslinking, thermal stability, thermal curing, etc.) of materials during processing by recording the reaction torque generated by the material to the rotor screw during the mixing process and the temperature changing with time, and it also can as an effective means of production control at the same time. Since the torque rheometer is similar in structure to the actual production equipment (internal mixer, single-screw extruder, twin-screw extruder, etc.), and it need small amount material, it can simulate mixing, extrusion and other processes in the experiment process, especially suitable for producing formulations, measuring products and optimizing process conditions.

Determination of rheological properties of polymer materials during processing
In the mixing process of polymer material in mixer, various control devices and test means are used to study the change process of material in solid state, high elastic state and viscous flow state and the reason for the change. The gel plasticization time and melt viscosity of polymer materials were studied.
The torque rheometer mainly consists of three parts:
1 A control system for setting experimental parameters and displaying experimental results;
2. Electromechanical drive system, used to control or display the experimental temperature, rotor speed, pressure, and torque changes with time;
3.The replaceable test parts are generally equipped with mixer device or screw extruder device as required:
The mixer (example Figure 1), consisting of a "∞" type detachable mixing chamber and a pair of rotors rotating at different speeds, opposite each other. In the mixing room, the rotor rotates toward each other, shear the material, so that the material is forced to mix in the mixing room; The two rotors have different speeds, to make material dispersive mixing in their gaps.
Features OF Torque rheometer
1. Advanced electric control, high reliability, easy to maintain;
2. Well-made, stainless steel bearing bushing, wearable and durable;
3. Abundant processing software, powerful function, fast and efficient, easy to operate;
4. High accuracy, high repeatability;
5. High cost performance;
6. Diagram output for speed, torque, temperature, pressure and time;
7. Methods and datas interchangeable between lab and automation equipment;
8. Possible to connect with mixer, extruder, calender, blown film unit, pelletizer, etc.
