The present invention relates to a polyolefin, a method for preparing the same, and a vehicle rear bumper beam using the same, and provides a polyolefin resin which is composed of a thermoplastic resin composite including a polymer base including a polypropylene homopolymer, which has a molecular weight distribution of 2 to 10, and a colorant, and a fiber reinforcing material that is impregnated into the polymer base and has a length of 5 to 20 mm, 10 to 50 wt% of the fiber reinforcing material being included with respect to the polyolefin resin, and which is thus able to maintain a low specific gravity while exhibiting improved mechanical properties and high impact strength, a method for preparing the same, and a vehicle rear bumper beam that can be injection-molded using such a polyolefin resin, thus minimizing production costs, and which achieves dimensional and performance stability, and thus can satisfy legally mandated low-speed crash performance.
