FT-NIR spectroscopy can quickly and non-destructively analyze the NCO% in polyurethane.
Polyurethane polymers are used in the production of foams, inks, adhesives, synthetic fibers and plastics.
Polyurethane polymers are usually and most commonly formed after the reaction of polyols and isocyanates. By measuring the NCO%, the development of the reaction can be monitored.
FT-NIR is an attractive alternative because it allows fast, non-destructive verification of NCO% in polyurethane. Each sample can be inspected within one minute, and can be tested by operators with no analytical background.
The FT-NIR method usually shows reproducibility that is not different from established laboratory techniques, but has excellent reproducibility and robustness.
This study illustrates the use of the ABB FT-NIR instrument (PTPA2000-260) to quickly determine the NCO% in polyurethane polymers.
Calibration NCO% Chart: Actual and Forecast
The research carried out by ABB proves the feasibility of NIR online monitoring of NCO%.
The experiment was carried out with a transflective probe. However, for industrial functions, it is recommended to use a transmission probe or a flow cell for higher repeatability and a simpler cleaning process.
