Woolley, W.D. and Field, P., 1971. A PRELIMINARY STUDY OF THE THERMAL DECOMPOSITION OF POLYURETHANE FOAMS BY ELEMENTAL ULTRAMICROANALYSIS. Fire Research Notes 880
ABSTRACT
A study of the thermal decomposition of certain rigid and flexible polyurethane foams has been undertaken by monitoring the nitrogen contents of the residues from decomposition experiments using elemental ultramicroanalysis. With the rigid foams the nitrogen content is lost in each case by a general temperature dependent fragmentation process whereas the flexible foams each show a rapid complete loss of nitrogen at low temperatures.
