Abstract:
1. Permeable flexible composite based on at least one peiforated and permeable carrier, which contains on at least one side of the carrier and inside the carrier at least one inorganic component, which comprises (A) and (B), which permeable flexible composite is obtained by application of a suspension to a perforated and permeable carrier and subsequently heating at least once during which said at least one inorganic component is solidified on and in the carrier, wherein the composite has a thickness from 5 to 1000 μm, and wherein the carrier has a mesh opening of 50 to 500 μm. wherein the suspension comprises a sol of at least one oxide of an element selected from the group consisting of metals, metalloids, and composition metals, obtained by hydrolyzing a nitrate, halogenide, carbonate or alcoholate compound of said element, and a compound of at least one element from group III to VII of the periodic system, the suspension containing no organic binder, wherein (A) is said at least one oxide of an element, and (B) is said compound; and wherein (B) has a particle size greater than the particle size of (A).
