Abstract
Provided are insulative apparatus and methods of forming insulative apparatus. As an example, a method of forming an insulative apparatus can include connecting a barrier material to a mold; injecting a polyurethane foam composition into the mold, wherein the polyurethane foam composition includes a polyol, an isocyanate, and supercritical carbon dioxide; curing the polyurethane foam composition to form a polyurethane foam and applying a vacuum to the mold to provide a pressure from 1 millibar to 500 millibar.
