Abstract
Wrap around closures for cables, pipes, splices, and junctions to effect repair, insulation, waterproofing and the like and a method for preparing such closures are described. The closures comprise generally rectangular sheets of heat shrinkable polymer having a large central section which has been hot stretched and cooled while in stretched condition and two small, flat unstretched end sections integral with the central section. Each end section has a layer of non-silicone adhesive covering one of its surfaces, optionally a layer of non-porous support material covering and adhering to the adhesive layer, a layer of silicone adhesive covering and adhering to the non-silicone support layer and a peelably removable cover layer covering the upper surface of the silicone adhesive layer. The several layers lie on the upper surface of one of the end sections and on the lower surface of the other end section.
