Process for preparing open-celled low density rigid polyurethane foam |
| abstract |
Method for the preparation of low density open celled water blown rigid polyurethane foams comprising the step of reacting a polyisocyanate component with a polyol composition containing a first polyol component comprising at least one polyoxyalkylene polyol having oxyethylene residues, said component having an average nominal hydro xyl functionality of 2 to 4, an hydro xyl number of not more than 60 mg KOH/g and an average oxyethylene content of less than 50 wt%; a second polyol component comprising at least one polyoxyalkylene polyol containing oxyethylene residues, said component having an average nominal hydroxyl functionality of 2 to 4, an hydroxyl number of not more than 135 mg KOH/g and an average oxyethylene content of at least 50 wt%, the amount of the first polyol being at least 70 wt% and the amount of the second polyol being at most 30 wt% and wherein said polyol composition does not comprise any polyol having a hydroxyl number of more than 150 mg KOH/g. |
