Webinar Part II: Advanced Rheometric Applications for Aging/Mutating Systems In this second part of the webinar series on rheometric applications, we explore advanced applications of Optimally Windowed Chirps (or OWCh) to characterize complex material systems, including aging thixotropic systems such as clay dispersions. We describe how user control of the initial phase and the frequency…
Webinar Part I: Basics of the Optimally-Windowed Exponential Chirp In this two‑part webinar, we illustrate how modern broadband rheometric techniques can be used to measure the material functions of what may broadly be referred to as mutating materials (or changing materials), with rheological properties that are both time‑ and frequency‑dependent. Numerous approaches have been proposed…
Overview The ability of a material to store and transfer heat is characterized with the material properties of thermal diffusivity, thermal conductivity, and specific heat capacity. Understanding these properties is critical when exposing a material to a wide array of temperature environments: large gradients, rapid changes, and maintaining stability, to name a few. Accurate…
Overview Adhesives are widely used across a broad range of industries and are a regular part of consumers’ daily lives. A quantitative understanding of the performance of such materials, such as adhesion, cohesion, tack, and peel performance is important for quality control and guiding formulators. Rheology is a powerful tool that provides direct measurement…
Overview Thermosetting materials, such as epoxy, have been widely applied in many areas including automotive, aerospace and electronics industries in the form of surface coating, structural adhesives, advanced composites and packaging materials. These kind of materials pose high mechanical strength, high temperature stability and good solvent resistance. Unlike thermoplastic polymers, the process of thermosets…
