Abstract
Provided is a polypropylene resin composition. The polypropylene resin composition includes: from about 20 to about 80 parts by weight of a polypropylene resin; from about 1 to about 35 parts by weight of an amine-based kenaf master batch; and from about 1 to about 25 parts by weight of a vinyl-based acetal compatibilizer. Also disclosed is the polypropylene resin composition which is used for vehicle interior and exterior materials, thereby improving physical properties such as low-temperature properties and tensile strength and providing superior resistance against damages.
