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.

Abstract: Polyurethane or polyisocyanurate foam stock and methods of manufacturing are described herein. The foam stock can include (a) a polyurethane or polyisocyanurate 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 present in an amount from greater than 50% to 90% by weight, based on the total weight of the foam stock. The density of the foam stock can be from 10 lb/ft3 to 35 lb/ft3. The flexural strength of the foam stock can be at least 100 psi. The resulting foam stock can be used to produce polyurethane or polyisocyanurate foam to be used in composite panels.
