The present invention relates to: a polyolefin resin composition for manufacturing foam, which comprises random polypropylene, polyolefin-based elastomers, and a nucleating agent, wherein a weight ratio of the random polypropylene to the polyolefin-based elastomer is 1 : 0.3 to 1 : 1; and to foam and molded articles manufactured from the composition. The polyolefin-based resin composition according to the present invention can be preferably used as a foam material applicable as a buoy due to excellent adhesion and mechanical properties and a low water absorption rate.
본 발명은 랜덤 폴리프로필렌; 폴리올레핀계 엘라스토머; 및 핵제를 포함하며, 상기 랜덤 폴리프로필렌과 폴리올레핀계 엘라스토머의 중량비는 1:0.3 내지 1:1인 것을 특징으로 하는 발포체 제조용 폴리올레핀계 수지 조성물, 이로부터 제조된 발포체 및 성형품에 관한 것이다. 본 발명에 따른 폴리올레핀계 수지 조성물은, 융착성 및 기계적 물성이 우수하면서 흡수율이 낮아 부표로 적용 가능한 발포 소재로서 바람직하게 사용될 수 있다.
