More Information
Summary: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.
