Preparation of thermally stable rigid polyurethane foam |
| abstract |
A process for the preparation of rigid polyurethane foams which are relatively stable at elevated temperatures involves reacting a polyether polyol reactant with an organic polyisocyanate reactant in the presence of a foaming agent comprising water. The polyol reactant is a select combination of three polyols and is effective in improving the thermal stability of the resulting foam without appreciably affecting its other physical properties. |
