본 개시 내용의 구현예는 단열 장치, 및 이러한 단열 장치의 형성 방법에 관한 것이다. 일례로, 단열 장치의 형성 방법은, 장벽 물질을 몰드에 연결하는 단계; 폴리우레탄 폼 조성물을 몰드 내에 주입하는 단계로서, 상기 폴리우레탄 폼 조성물은 폴리올, 이소시아네이트 및 초임계 이산화탄소를 포함하는, 단계; 상기 폴리우레탄 폼 조성물을 경화시켜, 폴리우레탄 폼을 형성하는 단계; 및 상기 몰드에 진공을 적용하여, 1 밀리바(millibar) 내지 500 밀리바의 압력을 제공하는 단계를 포함할 수 있다. 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.
