Abstract
The elastomeric composition for preparing an olefinic elastomer crosslinked foam according to the present invention contains an ethylene/&agr;-olefin copolymer (A) having a specific density and MFR, an organic peroxide (D), a crosslinking assistant (E), a foaming agent (F), an organic metal compound (G), and as necessary, a high pressure low density polyethylene (B) having a specific MFR, and an ethylene/vinyl acetate copolymer (C) having a specific amount of vinyl acetate and a specific MFR. An olefinic elastomer crosslinked foam of the present invention can be obtained by crosslinking and foaming the above composition. Further, another olefinic elastomer crosslinked foam of the present invention can be obtained by a secondary compression of the above crosslinked foam. The footwear part of the present invention is made of these crosslinked foams. The present invention provides an elastomeric composition for preparing an olefinic elastomer crosslinked foam that can provide an olefinic elastomer crosslinked foam having an Asker C hardness of 20 to 80, a low specific gravity, a low compression set, and excellent tear strength and impact resilience; and a crosslinked foam made of this. Furthermore, the present invention provides footwear parts made of the above crosslinked foam.
