Standard Test Method for Polyurethane Raw Materials: Determination of Primary Hydroxyl Content of Polyether Polyols
|Publication Date:||1 April 2018|
|ICS Code (Thermoplastic materials):||83.080.20|
Carbon-13 Nuclear Magnetic Resonance Spectroscopy (13C NMR) measures the primary hydroxyl content of ethylene oxide (EO)-propylene oxide (PO) polyether polyols used in preparing flexible polyurethane foams. This method is best suited for polyether polyols with primary hydroxyl contents of 10 to 90 %.
The values stated in SI units are to be regarded as standard.
