Patent ID: 7468205

Claim:
A multilayer composite material comprising at least three layers, wherein at least one layer is an aerogel-containing layer, which comprises aerogel particles and a binder and wherein the aerogel particles are present in an amount which ranges from 5 to 97 vol. %, and the other two layers do not contain aerogel particles and comprise materials selected from the group consisting of fusion adhesives, plastisols, thermosetting resins, transparent or translucent synthetics, and foams and have a thickness of more than 100 microns, wherein the three layers form a “sandwich” structure in which the aerogel-containing layer is arranged between the two other layers and wherein the binder in the aerogel-containing layer is selected from the group consisting of ethylene vinyl acetate copolymers, polyamides, formaldehyde condensates, polyimides, polybenzimidazoles, cyanacrylates, polyvinyl alcohols, polyvinyl butyrals, polyethylene waxes, anaerobic adhesives, moisture-setting silicones, photo-setting systems, UV-setting systems, methacrylates, two-component silicones, cold-setting epoxide resins, and cold-setting polyurethanes.
