| description | The invention relates to polyurethane foams comprising oligomeric polyols. In embodiments of the invention, the polyurethane foams comprise the reaction product of: (a) a polyisocyanate; and (b) an active-hydrogen containing composition comprising an oligomeric polyol having a hydroxyl number of about 45 to about 65 mg KOH/g, a number average hydroxyl functionality (Fn) of less than about 2.7, and about 40% weight or greater oligomers. The polyurethane foams of the invention may be slabstock foams or molded foams. Also disclosed are low odor polyols and polyurethane compositions.
L'invention concerne des mousses de polyuréthane comprenant des polyols oligomériques. Dans des modes de réalisation de l'invention, les mousses de polyuréthane comprennent le produit de réaction (a) d'un polyisocyanate et (b) d'une composition contenant de l'hydrogène actif comprenant un polyol oligomérique avec un nombre hydroxyle d'environ 45 à environ 65 mg de KOH/g, une fonctionnalité (Fn) hydroxyle moyenne inférieure à environ 2,7, et environ 40% en poids ou plus d'oligomères. Les mousses de polyuréthane de l'invention peuvent être des feuilles de mousse ou des mousses moulées. L'invention concerne également des polyols à faible odeur et des compositions de polyuréthane. |
