Dynamic-Mechanical Thermal Analysis (DMTA)
The Physica MCR rheometers not only carry out rheological measurements in shear, but can also be used for material characterization in torsion and extension. In combination with the convection heating systems CTD 450 and CTD 600, the instruments carry out the dynamic-mechanical thermal analysis (DMTA) of solids as well as films and fibers. The system's large temperature range allows the characterization of material properties from the glassy to the rubber state and the melting point.
Material characterization
- Measurement of solids in torsion and extension
- Determination of the glass transition temperature, melting point and other transition temperatures
- Relaxation measurements
- Investigation of material properties as a function of temperature with higher sensitivity than DSC
- Multiwave analysis to measure the frequency dependence of transition processes
The tools
- Convection heating systems CTD 450 and CTD 600 >> with excellent temperature accuracy and stability from -150 ºC to +450 ºC (+600 ºC)
- Solid torsion bar fixtures accomodate samples with rectangular or circular section up to a length of 50 mm
- Sample thickness for rectangular samples: 0.25 to 12 mm
Sample diameter for circular samples: 0.5 to 7 mm
- Tension measurements with Universal Extensional Fixture (UXF) for thin films and fibres with Quicksnap system for easy sample loading
- Sample monitoring as well as image or video recording during the measurement with the Digital Eye camera and CTD 450
- Multiwave capability
- Recording and presentation of all torsional and extensional data with the RheoPlus software
- Wide range of workbook templates including analyses for the determination of transition points, slopes etc.
