摘要： Disclosed is a resin composition for improving a whitening resistance in bending deformation. The flame retardant polypropylene-based resin composition with an improved whitening resistance in bending deformation according to the present invention includes a polypropylene-based resin, a polyolefin elastomer, a modified polyolefin elastomer grafted with polar groups and an inorganic flame retardant, wherein the polypropylene-based resin is included at a content of 5 to 50 % by weight of the total composition, wherein the polyolefin elastomer is included at a content of 0.1 to 50 % by weight of the total composition, wherein the modified polyolefin elastomer grafted with polar groups is included at a content of 0.1 to 30 % by weight of the total composition, and wherein the inorganic flame retardant is included at a content of 30 to 75 % by weight of the total composition. The resin composition according to the present invention may be used as a coating material of electrical wires, and therefore may be useful to minimize a whitening phenomenon in bending deformation without deteriorated physical properties such as tensile strength, tensile elongation, etc.
