The polymer characterization technique categories are: chemical, electrical, mechanical, molecular, physical, rheological, spectroscopic, thermal property, thermal transition and viscoelasticity. The interactions among the functional groups, chain orientation, structural changes upon treatment/modification, and interfacial properties of the polymeric composite are some of the interesting information that can be revealed from the Raman spectra. Recycled polymer material characterization When working with new compounds and sustainable, recyclate-based material formulations – gaining full confidence in their performance requires accurate assessment of not only physical and mechanical properties but also the identification and mitigation of any contaminants. These techniques are typically used to study curatives, formulations, resins and filled systems, either during processing or as final products. Polymer Electrolytes is a comprehensive and up-to-date guide to the characterization and applications of polymer electrolytes. 2. The sample is scanned at a wavenumber range of 4000 to 400 cm1. In addition to these techniques, other physical properties may need to be measured to pinpoint the grade of polymer, such as melting point determination by DSC, Durometer hardness and specific gravity measurements. Given the level to which plastics, rubbers, and other materials have impacted modern life, it is easy to see the importance of in-depth polymer analysis.
