Abstract

A polyolefin-based thermoplastic elastomer and a crosslinked body of the same which can undergo a silane-crosslinking process excellent in productivity and have a rubber property required as a substitute material for EPDM is disclosed herein and can use a silane-crosslinkable ethylene-propylene copolymer characterized in that an organic peroxide (B) and a silane coupling agent (C) are compounded with an ethylene-propylene copolymer resin (A) which comprises 5 to 25% by mass of an ethylene component and 75 to 95% by mass of a propylene component, and whose MFR measured at 230° C. and with a load of 2.16 kg applied is 20.0 g/10 min or less. and further a compounded amount of the organic peroxide is 0.1 to 0.6 pts. mass based on 100 pts. mass of the ethylene-propylene copolymer resin (A) and a one-minute half-life temperature of the organic peroxide is 175.2° C. or less.
