Polyisocyanurate foams containing dispersed non-porous silica particles

摘要

Disclosed herein are polyisocyanurate and/or polyurethane foams containing non-porous silica particles derived from mesoporous cellular foams, wherein the polyisocyanurate and/or polyurethane foams have enhanced heat and/or fire resistance. Processes for making such foams and methods of using them are also disclosed.
