ABSTRACT:
A heat-shrinkable, tubular foam can be produced from a composition which comprises 100 parts by weight of an ethylene-.alpha.-olefin-nonconjugated diene copolymer, 1 to 20 parts by weight of a foaming agent, 5 to 100 parts by weight of a thermoplastic resin having a vicat softening point of 50.degree. to 200.degree. C., and up to 10 parts by weight of a crosslinking agent, by shaping the composition into a tube, crosslinking and foaming the tube and pressurizing the tube in the interior to inflate it. This heat-shrinkable, tubular foam is best suited for jacketing pipes, hoses, and the like.
