摘要：
The present invention relates to a thermal insulating composition, containing 5 to 60% by weight of a hydrophobized granular material comprising fumed silica and at least one IR-opacifier, and 40 to 95% by weight of an inorganic and/or an organic binder, whereby the hydrophobized granular material has a content of free hydroxyl groups of no greater than 0.12 mmol/g, as determined by the reaction with lithium aluminium hydride.
