Supplier documentation outlines physical specifications, not the chemical footprint of the polymer on the bench. When a recycled industrial feedstock carries hidden polypropylene, or an automotive part contains an unidentified plasticizer, the analyst has to identify each component and quantify it.
This compendium shows how thermal and infrared techniques produce those answers with minimal sample preparation, often in a single run. Three worked cases—unknown identification, recycling contamination, and additive analysis—give labs a working picture of where these instruments fit in polymer QA across modern manufacturing.
Download the compendium to:
- See how a single thermogravimetric analysis (TGA) run resolves an unverified polymer sample into five quantified components
- Read the calibration model that pinpoints polypropylene contamination in post-consumer high-density polyethylene (HDPE) to within ±0.19 percent
- Examine how coupled thermogravimetric-infrared (TG-IR) spectroscopy catches the additive evolving from a chlorinated cable sheath
