Abstract:
1. A foam obtained by foaming an olefin polmer wherein the foam has a specific gravity (d) in the range of 0.03 to 0.30, and a compression sct (CS, %) and the specific gravity (d) satisfies the following formula: and wherein the foam is obtained by heating an ethylene polymer composition comprising an ethylene polymer (A) in an amount of 85 mass % to 93 mass % and an ethylene/propylene/non-conjugated polyene copolymer (13) in an amount of 7 mass % to 15 mass % (the sum of (A) and (B) is 100 mass %) and a azodicarbonamide (C) in an amount of 5 to 6 parts by mass relative to the total 100 parts by mass of the olefin polymers, wherein the non-conjugated polyene is 5-ethylidene-2-norbornene and/or 5-vinyl-2-norbornene: the component (A) comprising (A1) an ethylene/1-butene copolymer in which (a1) a density (ASTM D1505, 23° C.) is in the range of 0.857 to 0.910 g/cm the component (B) satisfying the conditions in which (b1) a ratio (Et/α) of a content (Et, mole %) of constitutional units derived from ethylene and a content (α, mole %) of constitutional units derived from propylene is in the range of 50/50 to 80/20, (b2) an iodine value is in the range of 0.5 to 50 (g/100 g), and (b3) a Mooney viscosity (ML
