WEBINAR: A MultiDrive Rheo-DMA Platform for Extended Polymer Analysis


March 24, 2020 at 2:00–3:00PM EDT
Webinar via Zoom

FREE for Everyone

Summary

Dynamic mechanical analysis (DMA) is a well-established technique for characterizing mechanical properties of all kinds of materials, particularly polymers or polymer-based products such as thermoplastics, thermosets, elastomers, adhesives, paints and coatings, films and fibers, as well as composites. A new measuring device concept is introduced which combines an electronically commutated (EC) motor as rotational top drive and a moving magnet linear drive or another EC motor, as bottom drive to enable rheological measurements and DMA on one single device. The concept enables various modes of operation by using different combinations of the bottom drive. Besides working in the rheological modes such as separate motor transducer (SMT), combined motor transducer (CMT), counter-rotation and counter-oscillation the device is suitable to perform dynamic mechanical analysis in bending, tension, compression, and torsion.

DMA can provide quantitative and qualitative data regarding:

  • Viscoelastic moduli and damping
  • Material structure and morphology
  • Relaxation behavior (Primary, secondary)
  • Influence of fillers and fibers in polymers
  • Crystallization/melting processes
  • Curing behavior

In this webinar, you will learn how DMA can be used to gain a better understanding of the viscoelastic and thermal properties of your material. The theoretical basics of DMA measurements will be covered along with the test methods and the information gained from those. Various DMA applications ranging from polymer plastics, rubbers to composites will be discussed and the flexibility and versatility of such a 2 in 1 device concept will be demonstrated for extended polymer characterization.
