Abstract
Thermal insulation which contains a plurality of contiguous hollow structures such as hollow spheres and an elastomer, preferably a silicone rubber, which fills the interstices between the contiguous structures. The insulation may be molded around a pipe by filling the space between the pipe and an annular jacket which is concentrically arranged around the pipe to be insulated with hollow structures, adding a thermosetting composition to fill the interstices between the structures while the structures are retained in their original position and thereafter curing the thermosetting compositions to an elastomeric solid.
