Specification:
Device model: Pyris Diamond
Manufacturer: Perkin Elmer
Country of manufacture: USA

Description of test:
DMTA analysis is one of the thermal techniques used to identify materials, especially polymers. DMTA can simply be defined as the application of an oscillating force to a sample and the analysis of the material's response to that force. The DMTA test makes it possible to detect thermal effects due to changes in the modulus of material loss behavior.

applications:
  • Elastic modulus, loss modulus, dissipation coefficient and stress as a function of temperature, frequency, or strain and study of viscoelastic behavior
  • Drawing the mechanical behavior of viscoelastic materials as a function of frequency and temperature
  • Creep test and stress dissipation test
  • Learn about molecular structure, molecular weight, molecular weight distribution and crystallization study
  • Baking study, baking kinetics and post-baking studies
  • Investigation of fuzzy behavior and the effect of additive on the compatibility of polymer blends
  • Determining beta and gamma transfer points
  • Determining the glass transition temperature of materials and investigating the dependence of glass transition temperature on frequency
