Continuous measurement of MFR and viscosity under real-time conditions with melt return.
Continuous measurement of MFR and viscosity under real-time conditions with melt return.
Online-Rheometer RTR/RTS-TD
The Real-Time Rheometer (RTR/RTS-TD) is the perfect solution for continuous monitoring and quality control of high and low viscosity polymers in production. It measures MFR (melt flow index) and viscosity under real production conditions and provides valuable insights into the rheological and molecular structure of your polymer melts in real-time.
Good to know
All GÖTTFERT Online-Rheometers are also available for operation in hazardous areas of danger zones 1 and 2 with classification „Gas-Ex: Ex II 2G Ex h IIC/IIB T2 Gb X“ and „Dust-Ex: Ex II 2D Ex h IIIC/IIIB IP65 Ta,max Db X“
Specification
Melt return
No melt is lost. The disposal and removal of melt is no longer necessary.
Short residence time
Due to the fact that the flow rate of the CS (circulating stream) is up to 100 times higher than the flow rate of the MS ( measuring stream), polymer-related degradation processes are prevented by the correspondingly short dwell times.
Large measuring range
As the circulating stream always ensures a sufficient flow rate, the measuring stream can be run at the lowest pump speeds. The usable control range is 1:1000. This corresponds, for example, to an MFR range of approx. 0.3–100g/10min with one set of dies. Changes in the molecular structure can be measured from a minimum shear rate of 0.1 1/s, wherein the residence time is drastically reduced by the CS.
Short response time
The short residence times resulting from the CS leads to a corresponding short response time when the material is changed.
