  • Process for polyurethane-modified polyisocyanurate foam with improved thermal stability
    Patent number: 8916620
    Abstract: A method for improving the thermal stability of polyurethane-modified polyisocyanurate (PU-PIR) foams is provided. Moreover, a process for producing the PU-PIR foams exhibiting improved thermal stability is provided. The foams have 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.
    Type: Grant
