The present invention relates to a polyolefin-based resin composition for manufacturing a foam, and a foam and a molded article produced from the polyolefin-based resin composition, respectively, the composition comprising: an atactic polypropylene; a polyolefin-based elastomer; and a nucleating agent, wherein the weight ratio of the atactic polypropylene to the polyolefin-based elastomer is from about 1: 0.3 to about 1: 1.1. The polyolefin-based resin composition according to the present invention exhibits excellent melting characteristics and mechanical characteristics, and is low in absorptivity, and thus can be preferably used as a foam material suitable for buoys.
本发明涉及用于制造泡沫的聚烯烃类树脂组合物以及分别由该聚烯烃类树脂组合物生产的泡沫和模制品,所述组合物包括:无规聚丙烯;聚烯烃类弹性体;和成核剂,其中无规聚丙烯和聚烯烃类弹性体的重量比为约1:0.3至约1:1.1。根据本发明的聚烯烃类树脂组合物表现出卓越的熔融特性和机械特性,并且吸收率低,因此可优选地用作适用于浮标的泡沫材料。
