Heat-shrinkable, tubular foam |
摘要 |
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 DEG to 200 DEG 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.
