| description | The present invention relates to a polypropylene resin composition which is characterized by containing (A) 65-75 wt% of high crystalline polypropylene base resin; (B) 15-25 wt% of one kind or more rubber elastomer selected from a group consisting of ethylene-butene rubber (EBR), ethylene-octene rubber (EOR), and mixture of the same; (C) 5-10 wt% of an inorganic filler; and (D) 1.5-3.5 wt% of a foamer. The polypropylene resin composition according to the present invention improves surficial curve to improve appearance of a molded product, and has excellent mechanical properties such as high strength to be useful to be applied to vehicle exterior material, especially a roof rack, and further contributes to lower vehicle weight by low specific gravity.
본 발명은 (A) (A) 고결정성 폴리프로필렌 베이스 수지 65 ~ 75 중량%; (B) 에틸렌-부텐 러버(EBR), 에틸렌-옥텐 러버(EOR) 및 이들의 혼합물로 이루어진 군으로부터 선택된 1종 이상의 고무탄성체 15 ~ 25 중량%; (C) 무기충전제 5 ~ 10 중량%; 및 (D) 발포제 1.5 ~ 3.5 중량%를 포함하는 것을 특징으로 하는 폴리프로필렌 수지 조성물에 관한 것이다. 본 발명에 따른 폴리프로필렌 수지 조성물은 표면 굴곡을 개선하여 성형품의 외관을 우수하게 하며, 고강성 등의 우수한 기계적 물성을 갖기에 자동차 외장재용 소재로 특히 루프랙에 유용하게 적용할 수 있으며, 나아가 저비중으로 인해 자동차의 경량화에 기여할 수 있다. |
