Dynamic mechanical analysis or DMA is an experimental technique that is often used to study and characterize the viscoelastic behavior of polymers. Apart from its several existing applications, it continues to find new applications in the development of novel and unique materials.
One of its emerging applications is in the definition of new formulations and their most efficient processing scenarios to obtain a desired property.
Evaluation of different rubber formulations is another field where,
performance characteristics of the rubber formulation can be
optimized through the use of DMA.
Hence, it is a very useful and powerful technique for both the resin formulators as well as the resin processors.
Read on to know more about the basics of DMA technique along with its several emerging applications.
Introduction and Basics of DMA
Dynamic mechanical analysis is an experimental technique that is often used to study and characterize the viscoelastic behavior of polymers. During the technique, a sinusoidal stress is applied to the material that is being tested. The strain in the material is then measured, allowing for a determination of the complex modulus. The temperature of the sample and the frequency of the stress are often varied, leading to variations in the complex modulus values.
