The present invention relates to a process for producing silica-based thermal insulation moulded body comprising at least 50% by weight of synthetic amorphous silica and not more than 50% by weight of natural silica with a specified particle size, thermal insulation moulded body obtainable by this process and the use thereof for thermal and/or acoustic insulation.
C04B 30/02 - Compositions for artificial stone, not containing binders containing fibrous materials
C04B 40/00 - Processes, in general, for influencing or modifying the properties of mortars, concrete or artificial stone compositions, e.g. their setting or hardening ability
Silicon dioxide-containing thermal-insulation sheet hydrophobized throughout with hardened surface, wherein the compressive stress at fracture measured on the sheet surface is higher than the compressive stress at fracture measured on the sectional surface in the middle cross section of the sheet parallel to the sheet surface, at, in each case, the same penetration depths of the measurement probe in the test specimen.
Vacuum insulation panels, methods for manufacture thereof, and applications thereof are described. The vacuum insulation panels comprise a porous insulating core encapsulated in an envelope to which a vacuum is applied. The envelope is coated with a waterproof coating layer which increases the robustness of the vacuum insulation panel.
