  • Heat-recoverable article
    Patent number: 6015600
    Abstract: An article (2) in which at least part of a surface (8) of a polymeric element has an embossed pattern (6). The article may be either heat-recoverable or non-heat-recoverable. If the article is heat-recoverable, when heated the article recovers and the embossed surface becomes substantially smooth. The change in surface texture can be used to indicate that sufficient heat has been applied to the article to achieve adequate recovery and/or to adequately melt an attached adhesive layer (10). In another embodiment, the article (2) is in the form of a patch (14) which can be used to secure the opposing longitudinal edges of heat-recoverable article which is in the form of a wraparound sheet.
