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.

Abstract: An article and method for preparing wraparound closures for cables, pipes, splices, and junctions to effect repair, insulation, waterproofing and the like are described. The article is a generally rectangular sheet of a plastic material which has the property of shrinking toward its original dimensions when it is heated after having been stretched at elevated temperature and cooled while in stretched condition. The sheet has a large central section which has been hot stretched and cooled and two small end sections which have not been stretched. The wrap-around closure is made by wrapping the sheet loosely around the object to be enclosed and bringing the two end sections together so that one overlays the other, one or both of the facing surfaces of the end sections is coated with a thin layer of a lower alkyl cyanoacrylate adhesive. The end sections rapidly and strongly adhere to each other. The wrap-around sheet is then heated to a temperature in the range about 250.degree.-375.degree.F.
