Analyzing Chemical Composition of Rigid Polyurethane (PU) Foams using FTIR Microscopy and DRIFTS-IR
- The chemical composition of rigid polyurethane foams was studied using FTIR microscopy and diffuse reflectance Fourier transform spectroscopy (DRIFTS) FTIR.
- Temperature gradients during the processing of rigid polyurethane (PU) foams leads to chemical gradients that might be observed across the radial and axial dimensions of the foam.
- Unreacted reactants and products from side reactions can remain trapped in the cavities of the foam hampering mechanical strength.
- A highly complex and heterogeneous polymeric composite results.
- The chemical composition of the cellular structure of the foam was studied with distinct spectra of the gas filled cell nucleus and cell wall.
- FTIR spectroscopy offers an ideal tool for studying variations in chemical composition at both bulk and microscopic levels.
