Abstract

Abstract A heat-shrinkable tube (1) is described, which is provided with a compound layer (2) on the inner surface. The compound layer (2) contains a polymerous compound containing an unsaturated bond, and a peroxide. This heat-shrinkable tube is suitable particularly for insulative covering of electronic parts or areas where they are fitted in electronic devices.
