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.
Detailed interpretation
- Top library match: Copolymerized PP #713
- No spectral features incompatible with polypropylene were observed.
- The exact comonomer type and content cannot be determined from the FTIR spectrum alone.
- The weak band at 1101 cm⁻¹ assigned to siloxane may reflect a silicate filler rather than a structural part of the polymer; further investigation is needed to confirm the filler nature.
