Polymer Material Analysis Techniques
This eBook showcases the various tools accessible to R&D and QA/QC environments for proactive characterization and troubleshooting of polymer materials.
Determining the Linear Viscoelastic Region in Oscillatory Measurements
This note will describe the linear viscoelastic region (LVR) and how to determine the LVR in oscillatory experiments for the purpose of obtaining quality data. All aspects of the LVR discussed in this note are general to viscoelastic samples, including (but in no way limited to) polymers, foods, gels, creams, pastes, slurries, emulsions, and inks.
Thermal Analysis of Phase Change Materials – Three Organic Waxes using TGA, DSC, and Modulated DSC®
The purpose of this study is to characterize three phase change materials (PCMs) – one paraffin wax and two beeswaxes. PCMs are widely used for thermal energy storage and thermal management due to their high latent heat storage ability.
Ash Testing of Formulated Products Using Thermogravimetric Analysis
Ash testing is a common technique used to determine the composition of materials. By heating a sample to high temperature in air all organic substances will pyrolyze leaving behind only inert and inorganic substances. This residue is then weighed to determine its weight percentage in the original material.
Determination of Composite Cure
Various thermal analysis techniques can be used to monitor the cure level in thermosets. Differential scanning calorimetry (DSC), for example, can determine cure level based on the amount of additional curing (with associated heat evolution) that occurs on further heating.
Thermogravimetry of Air Sensitive Materials
This 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.
Time Dependent Stability of Aqueous Based Anode Slurries with Bio-Derived Binder by Rheological Methods
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.
Determination of Polymer Blend Composition
The blending of two or more polymers is becoming a common method for developing new materials for demanding applications such as impact-resistant parts and packaging films.
Isothermal Microcalorimetry to Monitor Bacteria Growth
There has been significant work done looking at using IMC to characterize the growth patterns of bacteria3-9 and even converting isothermal microcalorimetry data into biologically meaningful data such as growth rate, lag phase, or maximum growth.
DSC Analysis of the Effect of Calcium Stearate on Crystallization of Polypropylene Nucleated with Sodium Benzoate – Modeling a PP Recycle Stream
This note demonstrates the utility of differential scanning calorimeter (DSC) measurements in evaluating the effects of an antagonistic interaction of two common additives that may be found in a mechanical recycle stream of polypropylene (PP).
