The REAL TIME RHEOMETER RTR/RTS is a capillary rheometer used in online quality control, which performs measurements on a continuous basis. The unit is used in production control and for monitoring high and low-viscosity polymers in the production and processing of raw materials.
Melt return flow:
No melt is lost and the removal of melt is no longer necessary.
Short residence time:
The flow rate of the circulating system (CS) is up to 100 times higher than that of the Measuring stream (MS). The corresponding residence times are short and prevent polymer degradation.
Large measuring range:
DThe flow rate of the circulating system (CS) is independently controlled, and therefore can always be made high enough to enable measurements at very low pump speeds in the measuring system. The effective control range is 1:1000, which corresponds to a MFR range of 0.3-100g/10min. Changes in the molecular structure can be measured from a minimum shear rate of 0.1 1/s (residence time is drastically reduced by the CS).
Short response time:
The short residence time results in a corresponding short response time when the material is changed.
