Latest Patents

Rolf Sommer holds a patent for a thermal insulating flexible ceramic that is based on a microporous oxide aerogel obtained from flame hydrolysis. This innovative material, particularly a silica aerogel, incorporates elastically bending or limply bending inorganic fibers along with possible additional additives such as opacifiers. The flexible ceramic contains a weight portion of about 10 to 30% of long fibers, which are over 10 mm in length and possess a comparatively high bulk density ranging from about 200 to 250 kg/m³, with an optimal density of about 350 kg/m³. Notably, this flexible ceramic does not require binders like phenol resin, yet it maintains high bending strength and exceptional resistance to breakage, even when subjected to multiple bendings around small radii. This technology allows for the production of pliable thermal insulating foils with thicknesses of less than 1 mm, which retain considerable shape stability while being easily bent and stamped.
