Abstract
Abstract A heat-recoverable article, especially a heat-shrinkable polymeric sleeve, is provided with an inner lining of a continuous metal foil to provide protection against inward water vapor transmission. The lining is preferably aluminium foil having a thickness of from 10 to 25 microns and is thus sufficiently thin that, on recovery, it leads to an even surface configuration without itself tearing or otherwise being damaged. The article is also preferably provided with central reinforcing means comprising one or more longitudinally compressible coils and is especially useful in the protection and insulation of splices in communication cables.
