ABSTRACT:
A heat-recoverable article which includes an outer layer of an opaque, dimensionally stable, thermoplastically deformable material and an inner layer of a cross-linked heat-recoverable (heat-shrinkable) material having a characteristic recovery shrinkage temperature. The outer layer has the property of becoming transparent at a decrystallization temperature which is at least as high as the shrinkage temperature, and preferably a few degrees higher, whereby the condition of the inner layer becomes visible through the outer layer when the article is heated to the decrystallization temperature.
