摘要： A crosslinked olefin elastomer foam has a specific gravity of 0.05 to 0.2, an expansion ratio of 8 to 15, a compression set of 30 to 60% and a tear strength of 1.5 to 2.5 kg/cm. The crosslinked foam is obtained by heating an elastomer composition comprising a specific ethylene/α-olefin copolymer, an organic peroxide, a crosslinking auxiliary and a foaming agent. The crosslinked foam has a high expansion ratio, is free from surface roughening attributed to defoaming, realizes a soft touch, exhibits a low compression set and is excellent in mechanical strength (particularly tear strength) and heat resistance.
摘要翻译：交联的烯烃弹性体泡沫体的比重为0.05〜0.2，发泡倍数为8〜15，压缩永久变形为30〜60％，撕裂强度为1.5〜2.5kg / cm。交联泡沫体通过加热包含特定乙烯/α-烯烃共聚物，有机过氧化物，交联助剂和发泡剂的弹性体组合物获得。交联泡沫体具有高膨胀率，不含由于消泡而导致的表面粗糙化，实现柔软的触感，显示低压缩永久变形，机械强度（特别是撕裂强度）和耐热性优异。

摘要： 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.
