Rigid fire retardant polyurethane foam |
| abstract |
A RIGID FIRE RETARDANT POLYURETHANE FOAM HAVING GOOD DIMENSIONAL STABILITY, MORE THAN 90% CLOSED CELLS AND A K FACTOR LESS THAN 0.13 IS PRODUCED BY REACTING WITH A POLYOL BLEND CONTAINING A SUCROSE POLYOL WHICH IS THE REACTION PRODUCT OF 8 TO 12 MOLS OF PROPYLENE OXIDE PER MOL OF SUCROSE OR A SUCROSE POLYOL WHICH IS THE REACTION PRODUCT OF 9 TO 12 MOLS OF PROPYLENE OXIDE PERMOL OD SUCROSE AN ISOCYANATO TERMINATED PREPOLYMER FORMED BY REACTING AN EXCESS OF A POLYMETHYLENE POLYPHENYL ISOCYANATE WITH A PHOSPHOURS-CONTANING POLYOL IN THE PRESENCE OF A BLOWING AGENT, SURFACTANT AND A CATALYST OF URETHANE FORMATION. THE RIGID FINE RETARDANT POLYURETHANE FOAMS THUS FORMED ARE PARTICULARY USEFUL FOR INSULATION PURPOSES. |
