Volatiles Present in Low Density Polyurethane Foams: Composition and Methods of Analysis

Polyurethane foam material for use in future vehicles were evaluated for their potential to contribute to light scattering films (LSF), Methods used included the fog test, infrared analysis for amines, and development of a technique for gas chromatographic analysis of organic extracts of foams. Process amines, including 1,3,5-tris (dimethylamino) pentane, were detected in two samples. Acetonitrile was found to be the most effective of six organic solvents for both direct extraction of foam and washing the film sample from the glass used in the fog test.
