Abstract
The invention concerns the use of a material comprising at least a crosslinkable elastomer selected from the group consisting of butyl rubber, halobutyls and brominated isobutylene and para-methylstyrene copolymers, and at least a non-crosslinkable elastomer with low thermal conductivity for thermal insulation, in particular for pipes. The invention also concerns a pipe, and, in particular a submarine oil pipe for great depths, comprising at least a layer of said material.
