Method of preparing aerogel-containing insulation article

摘要

The invention provides a method of preparing an insulation article comprising: (a) providing a sealed first container comprising aerogel particles under a first air pressure that is less than atmospheric pressure, wherein the unrestrained volume of the aerogel particles at the first air pressure is less than the unrestrained volume of the aerogel particles under a second air pressure that is greater than the first air pressure, (b) placing the sealed first container in a second container, (c) breaching the sealed first container to equalize the air pressure as between the first and second containers at the second air pressure and to increase the volume of the aerogel particles, thereby forming the insulation article. The invention also provides an insulation article obtainable by the method of the invention.
