Isocyanurate foam and method for producing the same |
| abstract |
A highly flame retardant and substantially non-combustible polyisocyanurate foam having low friability and no bursting characteristics and method for preparing the same. The method includes the step of reacting an isocyanate having an average isocyanate equivalent weight between about 135 and 145 with a polyether polyol having a hydroxyl number between about 300 and about 600 and a hydroxyl functionality of at least 3. The compounds are combined in amounts to provide NCO/OH equivalent ratio between about 10 and about 50 and are reacted in the presence of a chlorofluorocarbon blowing agent and a catalyst having the general formula:n wherein R is a hydrocarbon having between about 1 and about 2 carbon atoms, R′ is an alcohol radical having between about 2 and about 3 carbon atoms, and R˝ is selected from the group consisting of hydrogen and an alkane group having between 1 and 8 carbon atoms. |
