Identification Result
89%The FTIR spectrum is dominated by strong aliphatic C–H stretching and bending absorptions consistent with a polypropylene‑based material. The reference library comparison returns Copolymerized PP as the top match (similarity 0.875), and the fifteen leading candidates are all polypropylene or PP‑copolymer formulations, confirming the polyolefin backbone FTIR In-Depth Interpretation was not selected for this task, so this section shows the library-search result only and no deep AI interpretation was run.
