Articles and methods are provided for enclosing an elongate substrate. A container is provided which is configured to receive the elongate substrate. A first polymeric sealing material having a first softening point and a first melt viscosity is positioned in the container. A second polymeric sealing material is positioned in the container between the first sealing material and an end of the container. The second sealing material has a second softening point lower than the first softening point and a second melt viscosity lower at a defined temperature than the fist melt viscosity.

Curable adhesive system

Recoverable fabric sleeve

A branch-off region at an end of a sleeve (2), enclosing for example a branch in a telecommunications cable, is sealed by a method which includes positioning at the end of the sleeve (2) some means for example a clip (1) or a filling piece that forms terminal conduits (3), positioning a heat-activatable adhesive (5) in the end, and activating the adhesive by a heating means such as an electrical heater.

Branch-off technique

A branch-off region at an end of a sleeve (2), enclosing for example a branch in a telecommunications cable, is sealed by positioning at the end of the sleeve (2) a clip (1) or a filling piece that forms terminal conduits (3), positioning a heat-activatable adhesive (5) in the end, and activating the adhesive by a heater such as an electrical heater.

A cable splice, branchout or termination has a heat recovered member (30) around one or more cable portions (33) extending out of an end of the member (30). The cable portion (33) is protected from physical damage and heat by placing around it individually a metal foil member (1), preferably aluminium of thickness 150-250 microns. The metal foil member is preferably coated with a hot melt adhesive (2) and a mastic (5) at distinct locations. A pressure sensitive adhesive (4) may also be provided to help secure the foil member (1) around the cable portion (33) before recovery of the outer member (30). Apertures (44) may be provided in the foil member (1) to allow passage therethrough of hot melt adhesive provided on the inner surface of the recoverable member (30).
