摘要

Disclosed is a resin composition for crosslinking/foam molding which comprises a resin ingredient, a blowing agent, and a crosslinking agent, wherein the resin ingredient is an ethylene/a-olefin copolymer that comprises monomer units based on ethylene and monomer units based on an a-olefin having 3 to 20 carbon atoms and satisfies all of the following: (1) to have a density of 860-950 kg/m3, (2) to have a melt flow rate (MFR) of 0.01-10 g/10 min, (3) to have a ratio of weight-average molecular weight (Mw) to number-average molecular weight (Mn), Mw/Mn, of 5.5-30, (4) to have a ratio of Z-average molecular weight (Mz) to weight-average molecular weight (Mw), Mz/Mw, of 2-4, and (5) to have a melt tension (MT) of 8 cN or higher.
