Abstract:
Polymer characterization in the past has been difficult. Modern analytical tools and techniques make it much easier to solve difficult problems like failure analysis and even deformulation. This report will introduce a methodical approach to solving these types of problems. A method map approach will be described utilizing multiple techniques such as EGA (Evolved Gas Analysis), thermal desorption (TD), Heart-cutting EGA (HC-EGA) and pyrolysis (PY) using an EGA/PY-3030D Multi-functional pyrolyzer (Frontier Laboratories, Ltd.) and GC/MS. This report will show how these techniques were used to find and identify a minor component in a polyethylene sample that was causing a product performance issue. In addition, an introduction to reactive pyrolysis (RxPy) will demonstrate how this technique can be used for identifying additional additives in these same polyethylene samples.
