INTRODUCTION Online Measurement Technology Our Highlight: The simultaneous detection of the MFR/MVR value, viscosity strectrum and the flow exponent n (MW/Mn) Beyond these many numerous options offer for example the possibility of the IR /UV or FTNIR determination. Furthermore the Online Rheometer can be modified to an At-Line Rheometer by adding an Extruder as a melt feeder (optional with fully automated Online Sampler for continuous material feeding). By the use of a 90° deflection head the measurement of elongation, the die swell or the flow instabilities (Shark Skin) of the melt can be...

ONLINE-RHEOMETER The Differences Individual properties, specified to your process In order to give a statement about material characteristicsas well as the processability an Online Rheometer delivers data continuously. So the process and the application define the measuring testing device. Here the overview: > Rheometer without melt return into the process (MBR/MBR-TD) • • • • • Especially suitable for small charges and often changing product Small inner volume to reduce the melt holding time Purge valve for fast product change Extendable with melt tensile measurement (RHEOTENS at melt...

MBR / MBR-TD MINI BYPASS RHEOGRAPH (MBR) One of the most outstanding features of the MINI BYPASS RHEOGRAPH MBR is its compact size. With a width of approx. 150 mm this system is one of the smallest Online Rheometer available. Even in tight space this new design can be installed without problems. The reduced weight of 30 kg only eliminates costly mounting arrangements. A new die change system makes die changes quick and easy. The MBR has been designed specifically for finishing and compounding processes, which typically have frequent product changes. Its compact size allows a simple and easy...

SSR SIDE-STREAM-RHEOMETER (SSR) The melt return Online Rheometer with its unique annular transfer line for one port hole installation The SSR annular clearance connection is compatible with the standardized M18x1,5“ bore (alternatively also M26 or M36 x 1,5“). So a flexible and quick installation is possible to any existing bore of the Extruder, which was prepared for example to a pressure or temperature sensor. This means a minimum of planning effort close to low costs, an expensive modification of the Extruder with a suitable adapter plate is not necessary. Other outstanding features: •...

The Real Time Concept - The soultion: RTR/RTS-TD Pressure transducer Measuring pumps Circulation pump The RTR was the first Online Capillary Rheometer on the market with its patented three-pump-system. The number of installations worldwide in the three digit range are a positive proof that the RTR has defined the best-in-class in Online Rheometry. Especially for low MI materials, it is crucial to generate the measurement results as fast as possible. This can take an ordinary rheometer (single pump) more than an hour. The independently controlled circulation pump in the RTR delivers the melt...

RTR/RTS-TD RTR/RTS-TD The REAL TIME RHEOMETER is a Capillary Rheometer used in online quality control, which performs measurements on a continuous basis. Its purpose is in production control and for monitoring high and low-viscosity polymers in the production and processing of raw materials. Important rheological variables in real-time mode are being supplied, which are used to access the properties of the polymer. The melt from the material supply line is fed back into the process stream by the REAL TIME RHEOMETER in a closed circuit after the test has been performed. Fresh melt is...

RTR/RTS-TD From Real Time Rheometer RTR to Real Time Spectrometer RTS-TD • By the use of the newly developed twin dies and the work of 3 or 4 pressure transducers a specified range of the viscosity function under single point conditions are saved continuously. As like a basic feature in the RTR of course the melt index and/or volume index (MFI / MVI) are being determined Measurement values are the MVR, the viscosity function and the flow exponent Online-Rheometer RTS-TD, double die measurement Laboratory melt index test device, multi weight measurement Comparison principle melt index...
