摘要: Polyurethane composites and methods of preparation are described herein. The methods of making the polyurethane composite can include mixing (1) at least one isocyanate selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, (2) at least one polyol, (3) an inorganic filler, and (4) an evaporative coolant in an extruder to form a mixture. The method also include extruding the mixture into a mold cavity, generating heat in the mold cavity from the reaction of the at least one isocyanate and the at least one polyol, and allowing the evaporative coolant to migrate to an interface between the mixture and the interior mold surface. The temperature of the mixture causes evaporation of the evaporative coolant at the interface thereby removing heat at the interface. Suitable evaporative coolants for use in the methods of making the polyurethane composites include hydrofluorocarbons and hydrochlorofluorocarbons.

摘要: Composite materials and methods for their preparation are described herein. The composite materials can comprise (a) a polyurethane and (b) from 35% to 90% by weight, based on the total weight of the composite, of a particulate filler dispersed in the polyurethane. The polyurethane can be 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. The one or more polyols that form the polyurethane comprise a high hydroxyl number polyol having a hydroxyl number of at least 250 mg KOH/g. In some cases, the one or more polyols that form the polyurethane can have a weight average equivalent weight of from 200 to 1100 amu. In some cases, the one or more polyols that form the polyurethane can include less than 5% by weight, based on the total weight of the one or more polyols that form the polyurethane, of one or more flexible polyols having a hydroxyl number of less than 150 mg KOH/g and a functionality of less than 3.
