Hi Dave, Not quite, they do use irradiation crosslinking to make the heatshrink tube, but the hotmelt adhesive is a completly separate layer. They do different combinations of tube and glue for different applications. Really cool are the pre-forms that look like a parallel tube but shrink down into two sises with a smooth transition. The mold the final shape and then streach it (hot) into a parallel tube. They also do multiple entry versions. Raychem are leaders in this. They also do shrink metal parts.

The outside becomes hard but still shrinks. The inside just melts into a goo when heated.
