More Benefits

• Some benefits and features were already listed on the RheoPower page:
• RheoPower offers new possibilities and standpoints in research and developments.
• You can simulate polymer viscoelastic properties with different form of MWDs even with bimodality without doing any expensive mixing or polymerization experiments.
• You get information of molecular structure as not only long chain branching (LCB), but also short chain branches (SCB) relates to elastic P’ and viscous P’’ constants.
• Databases give possible to store chronology all studies, experiments and polymerization results, which are possible to give access to your colleagues in your intranet.
• Possible measurement or manner errors with rheometers are obtained immediately during analyses.
• You get more understanding of chain orientation effects during melt flows related to structure and at end user devices.
• On good platform by control theory, you can go further macro and micro structure research.
• Shown advantages are only a small portion and top of iceberg you can find yourself in your further studies.

The red measured viscosity function and yellow marked range in use. The blue fit viscosity function has a wider range. Also on right is shown the computation results as MWD and data label of polymer. Click on the figure to zoom it.

Shortly Background

There have been established linear relation between Rheologically Effective Distribution (RED) and flow for diffrent states. This excellent relation can be used to the quick and accurate detection of MWD. Thus this relation can be used for structure analyses, daily quality control at polymerization plants and as a design aid for new tailored polymers or extrusion, injection and other manufacturing methods.

Yes, this sounds too good to be true. After studying these public web-pages and later on with trial software and demos you can decide for your self. Let's first give the software a chance to speak for its self. You can study complete theory included with RheoPower later.

Graphical demonstration of the system using Control Theory and the nanostructure model of a polymer melt. Relative diameters of the statistical tube for molecules of different sizes produce the accurate Rheologically Effective Distribution (RED), which is subsequently converted to the MWD through melt calibration. The signal bump is shown to observe and separate RED or MWD. Unified Model sets accurate linear relation between REDs and different type viscoelastic flows. Click on the figure to zoom it.

The software family

The principal software RheoAnalyzer (VIS-MWD) and modern SQLite database architecture presents the backbone for the complete software family. The daily quality control at polymerization plants and design aid for new tailored polymers are given first consideration. Modern flexible technique offers rapid scalability for special applications.
