Simple Determination of the Linear Viscoelastic Region of a Polymer Using a Rheometer

Application Notes, Rheology Notes

Materials such as polymers exhibit viscoelastic behavior which is directly related to molecular structure and formulation differences. To accurately evaluate the relationships between molecular structure and viscoelastic behavior requires that experiments, such as rheological measurements, be conducted in regions where the viscoelastic properties observed are independent of imposed stress or strain levels. That is, experiments must be conducted in the linear viscoelastic region.

Stability Testing of Energetic Materials by Isothermal Microcalorimetry

Microcalorimetry, Videos, Webinars

Stability Testing of Energetic Materials by Isothermal Microcalorimetry Overview This webinar introduces the use of isothermal microcalorimetry for stability measurement of energetic materials. Energetic materials refer to materials, chemicals and substances which exhibit a risk for self-decomposition associated with self-heating ultimately resulting in run-way reactions. Such materials include propellants, percarbonates and peroxides, and these…
