IMPROVED THERMAL STABILITY OF POLYURETHANE-MODIFIED POLYISOCYANURATE FOAM
摘要
<p>A polyurethane-modified polyisocyanurate (PU-PIR) foam exhibiting improved thermal stability is provided. The foam has incorporated therein a high molecular weight ammonium polyphosphate (APP). APP is employed as a partial or complete substitute for flame retardants conventionally employed in PU-PIR foams. The foams of the invention exhibit excellent and improved thermal stability characteristics as compared to foams to which no APP has been added.</p>
