This application note will investigate the slurry aging and stability through its flow behavior and viscoelastic properties by using rheological methods. The slurry studied demonstrates a decrease in stability over time, which can be used to indicate the appropriate batch lifetime in a production environment.
DetailsIn this TA TechTip, we walk through the proper steps for installation and calibration of the three point bending clamp for the Discovery DMA850
DetailsThis note illustrates the advantages of working with a thermogravimetric instrument in an inert environment by way of a simple example with a water sensitive material.
DetailsOverview Thermogravimetry (TGA) is a classical method determining temperature dependent material properties. Traditional TGA is performed at ambient pressure and with relatively inert reaction gases. To measure application-relevant material properties, however, TGA must be performed under real application conditions: at high pressures, with reactive and/or corrosive gases and in steam atmospheres. The TGA and…
DetailsIn this note, TGA will be performed on natural and synthetic graphite of various particle sizes. The analysis will provide information that would find value in quality control settings, such as batch consistency and impurities.
DetailsThermodynamic Rules To Achieve High Binding Affinity & Selectivity High affinity and selectivity are two essential properties of drug molecules. Since the binding affinity is determined by the sum of enthalpic and entropic contributions, extremely high affinity necessitates optimization of both contributions to binding. An efficient approach requires accurate prediction of the contributions of specific…
DetailsOverview 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…
DetailsRheology is an indispensable tool to characterize structural molecular changes induced due to processing conditions and processing time.
DetailsThis note investigates the degradation kinetics of virgin and recycled polyethylene terephthalate fibers used for 3D printing through TGA, finding similar lifetime predictions for the samples studied.
DetailsIn this work, the thermal degradation process of nylon 66 was studied using TGA-MS, TGA-FTIR and TGA-GC/MS in inert gas environments. These techniques together can provide a lot of insights of the thermal degradation process and its off-gas products.
