Key Features Dynamic-Mechanical Thermal Analysis (DMTA)

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 differential scanning calorimetry (DSC)
• Multiwave analysis to measure the frequency dependence of transition processes

The tools

• Convection heating systems CTD 450 TDR and CTD 600 TDR with excellent temperature accuracy and stability
• Solid torsion bar fixtures accomodate samples with rectangular or circular section up to a free length of 50 mm
• Sample thickness for rectangular samples: 0.25 to 12 mm
  Sample diameter for circular samples: 0.5 to 15 mm
• Tension measurements with Universal Extensional Fixture (UXF) for thin films and fibers with QuickSnap system for easy sample loading
• Sample monitoring as well as image or video recording during measurement with the Digital Eye camera
• Recording, analysis, and presentation of all torsional and extensional data within the Rheometer Software RheoCompassTM
• Wide range of straightforward workbook templates including analyses for the determination of transition points, slopes, etc.
