Polymer FTIR Spectra

Polymer FTIR spectra provide definitive molecular fingerprints for plastic identification — characteristic C–H stretches and deformations, carbonyl bands, and backbone vibrations that distinguish polyethylene from polypropylene, PET from PVC, and nylon from polyester. These mid-infrared signatures are the industry standard for polymer characterization.

FTIR polymer identification drives recycling facility sorting, failure analysis, incoming material verification, and regulatory compliance in packaging, automotive, and medical device manufacturing. Browse polymer FTIR reference spectra on SpectralBench — identify absorption bands interactively, compare your unknown plastic samples, and download data as CSV or JCAMP-DX.
