DMA Principles and Basic Applications
This webinar explains the basic DMA principles and at the same time introduces a high-performance DMA instrument for carrying out various applications.
Dynamic mechanical analysis (DMA) is one of the most important techniques in thermal analysis. It can be used to study the viscoelastic properties and behavior of a wide range of materials as a function of temperature or frequency. This helps to ensure that suitable materials with the right mechanical properties are used. The types of materials that can be analyzed include thermoplastics, thermosets, elastomers, adhesives, paints and lacquers, films and fibers, composites, foodstuffs, pharmaceuticals, fats and oils, ceramics, constructional materials and metals.
What Exactly can DMA Measure?
Depending on the measurement mode, DMA determines either the shear modulus (G), or the Young’s modulus (E).
DMA provides quantitative and qualitative information on:
- Damping characteristics and viscoelastic behavior
- Polymer structure and morphology
- Primary and secondary relaxation behavior
- Crystallization processes
- Influence of fillers in polymers
This kind of information is very important for process and application engineers, materials research scientists, and physical chemists.
