Abstract: Polyurethane foams and methods of manufacturing are described herein. The foam can include (a) a polyurethane formed by the reaction of (i) one or more isocyanates selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, and (ii) one or more polyols; and (b) a filler. The amount of filler in the foam can be from 50 to 90% by weight, based on the total weight of the foam. The filler can include a plurality of fibers and/or a particulate filler. The polyurethane foams described herein are made without adding a surfactant to the reaction mixture. The density of the polyurethane foam can be at least 5 lb/ft3.
