A method of forming an insulative apparatus, comprising:
- 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.
An insulative apparatus comprising:
- a mold;
- a barrier material connected to the mold;
- and
- a polyurethane foam inside the mold, wherein the polyurethane foam is formed by injecting a polyurethane foam composition into the mold and curing the polyurethane foam composition, wherein the polyurethane foam composition includes a polyol, an isocyanate, and supercritical carbon dioxide, and wherein a vacuum is applied to the mold to provide pressure from 1 millibar to 500 millibar.
