Abstract

A conductive polymeric heat recoverable article is provided with electrodes (10) on its surface. The electrodes (10) can be connected to a source of electrical power to cause current to flow through the article to heat and hence to recover the article. However the arrangement is such that although the regions of the article immediately beneath the electrodes (10) may comprise heat recoverable material, those regions are not heated to a temperature sufficient to recover them. Therefore although the region of the article between the electrodes (2', 2'') recovers, the regions immediately beneath the electrodes (10) do not. So the electrodes (10) remain in contact with the article.
