| 20140171530 | Method of Making Foam - A method of making a foam from a polymerizable resin includes the following steps. A thermally-activated initiator having a temperature below the initiation temperature is combined with an elevated-temperature solution having the polymerizable resin and carbon dioxide at a temperature above a promoted temperature to create a resulting mixture having a temperature above the promoted temperature. The resulting mixture is expanded by decreasing the pressure of the mixture to create a froth having a plurality of cells formed by carbon dioxide that expanded out of solution. The polymerizable resin within the froth is cured to create a foam. | 06-19-2014 |
