Abstract

The invention relates to articles which comprise a heat-recoverable member composed of a conductive polymer composition and which are caused to recover by passing electric current through the member to cause resistive heating thereof. The invention resides in providing such an article with an electrode in the form of a metallic sheet containing an array of apertures e.g. a flattened expanded metal or a mesh of welded wires which allows the sheet to recover with the heat- recoverable member. Articles in the form of tape are particularly useful for covering electrical cables, including telephone cables.
