Process of producing urethane-modified polyisocyanurate foams |
摘要 |
A process for producing urethane-modified polyisocyanurate foams in which a poly(oxyalkylene-oxyethylene)polyether polyol is used as a modifying agent having the number of functional groups and the molecular weight in specific ranges with the equivalent ratio of NCO/OH being in a specific range and containing a specific quantity of ethylene oxide. The use of this modifying agent provides urethane-modified polyisocyanurate foams exhibiting excellent fire resistance and adhesion to an object surface.
