  • FLAME, SMOKE AND TOXICITY RETARDANT COMPOSITION FOR USE IN POLYURETHANE/POLYISOCYANURATE COMPRISING FOAMS
    Publication number: 20230043804
    Abstract: A reactive mixture comprising a Fire, Smoke and Toxicity retardant (FST) composition for making a polyisocyanurate and/or polyurethane (PIR/PUR) comprising material, said FST composition comprising: a) at least one compound having at least one ethylenically unsaturated moiety having a number average equivalent weight<160 g/mol, and b) optionally one or more radical initiator compound characterized in that the onset temperature for radical polymerization (Tonset) of the ethylenically unsaturated compound with or without the radical initiator is 2° C. up to 40° C. lower than the maximum reaction temperature achieved during the process for making the PIR/PUR material (reaction exotherm (Treaction)).
