Identification Result
79%The sample is identified as a polyester resin, consistent with a terephthalate-based polyester, based on a strong library match to commercial polyester resin (similarity 0.766) and corroborating spectral features indicative of an aromatic polyester 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.
