POLYPROPYLENE RESIN COMPOSITION AND OUTER PARTS OF VEHICLE USING THE SAME

摘要

The present invention relates to a polypropylene resin composition and an outer material of a vehicle using the same, and more specifically, to a polypropylene resin composition with improved heat resistance and molding shrinkage and a vehicle outer material using the same, wherein the polypropylene resin composition comprises 40-55 parts by weight of a base resin in which ethylene-propylene-butene copolymer is mixed with ethylene-propylene copolymer; 20-25 parts by weight of glass fiber; 10-20 parts by weight of ethylene-butene elastomer; and 1-5 parts by weight of a surfactant, and has low specific gravity and excellent physical properties such as high strength, impact resistance, etc., thereby having excellent resistance against breakage and significantly reducing deformation due to loads.
