The present invention relates to a sound absorbing and insulating material for a vehicle and, more specifically, to a sound absorbing and insulating material for a vehicle, comprising: a soft layer; and a hard layer which is formed on one surface of the soft layer and includes low crystalline propylene produced using a metallocene-based catalyst. Therefore, the sound absorbing and insulating material for a vehicle, having the above structure, provides excellent tensile strength, elongation, and tear strength by forming the hard layer including low crystalline propylene produced using the metallocene-based catalyst.

    본 발명은 자동차용 흡차음재에 관한 것으로, 더욱 상세하게는 소프트층 및 상기 소프트층의 일면에 형성되며, 메탈로센계 촉매를 사용하여 제조된 저결정성 프로필렌을 포함하는 하드층으로 이루어진다. 상기의 구조로 이루어지는 자동차용 흡차음재는 메탈로센계 촉매를 사용하여 제조된 저결정성 프로필렌이 함유된 하드층이 형성되어 우수한 인장강도, 신율 및 인열강도를 나타낸다.
