PROBLEM TO BE SOLVED: To provide an injection molding having predominant environmental deterioration resistance, wear resistance, durability and mechanical strength and excellent sense of touch (flexibility). SOLUTION: The injection molding comprises a partly or completely crosslinked composition containing (A) 1 to 99 pts.wt. of an ethylene-α-olefin copolymer manufactured of ethylene and 6-12Cα-olefin by using a metallocene catalyst, (B) 1 to 99 pts.wt. of propylene resin [a total amount of (A) and (B) is 100 pts.wt.] in such a manner that a crosslinking degree of the (A) ethylene-α- olefin copolymer is 50% or more and a swelling degree is 5 to 40%. A weight ratio of the 6-12Cα-olefin occupying in the ethylene-α-olefin copolymer is 30 to 60 wt.%, and a density of the (A) ethylene-α-olefin copolymer is 0.80 to 0.86. |
