Strip comprising a polymeric material filled with hollow microspheres (foam). This multilayer tape intended to be wound helically around a tubular structure for its thermal insulation, comprises a layer of the foam mechanically secured to at least one other layer of a polymeric, thermoplastic and / or elastomeric composition, the two layers extending over the entire length of the strip and each showing in radial section a determined thickness, the thickness of the foam being between 0.5 mm and 50 mm and representing at least 50% of the total thickness of the strip, the thickness of the other layer being between 50 mum and 5 mm. |
