Abstract:
A cross-linkable composition with controlled cross-linking as a material is used for fixing and thermally insulating tubes used for casing in drill holes, especially oil drill holes, during exploitation operations, such as oil extraction, in the drill hole. The cross-linkable composition includes at least one diene polyol, at least one polyisocyanate, and at least one heat insulating liquid filler.
