Zusammenfassung:	The present invention relates to a multi-component polypropylene composition for a pressurization type reservoir tank, including: high-melt strength polypropylene (HMS-PP) having a weight average molecular weight of 600,000 g/mol-750,000 g/mol; random polypropylene (random PP) having a weight average molecular weight of 300,000 g/mol-400,000 g/mol; block polypropylene (Block-PP) having a weight average molecular weight of 400,000 g/mol-600,000 g/mol; and 1000-4000 ppm of a nucleating agent. The multi-component polypropylene composition can be applied to a pressurization type reservoir tank requiring mechanical properties, impact resistance and transparency at the same time. 본 발명은 600,000 g/mol 이상 750,000 g/mol 이하의 중량평균분자량을 가지는 고용융장력 폴리프로필렌(high melt strength PP; HMS-PP); 300,000 g/mol 이상 400,000 g/mol 이하의 중량평균분자량을 가지는 랜덤 폴리프로필렌(Random-PP); 400,000 g/mol 이상 600,000 g/mol 이하의 중량평균분자량을 가지는 블록 폴리프로필렌(Block-PP); 및 1000 ppm 이상 4000 ppm 이하의 핵제를 포함하는, 가압식 리저버 탱크용 다성분계 폴리프로필렌 조성물에 관한 것이다.
