  • Aerogel-in-foam thermal insulation and its preparation
    Patent number: 6136216
    Abstract: Insulative compositions are prepared by agitating an aqueous mixture of aerogel and gelatin. Insulation obtained with such methods is non-toxic, environmentally safe, fire resistant with low smoke, has good handling properties, and provides low thermal conductivities. The insulation can be made in sheets, loose fill, or can be molded into particular shapes to provide particular types of insulation such as pipe insulation.
