Abstract: The present invention provides a TPO blend that exhibits surprisingly excellent low temperature impact resistance. The TPO blend according to the invention includes a polyolefin, a metallocene catalyzed olefinic copolymer plastomer and a lubricant package. The lubricant package includes a mixture of an internal lubricant and an external lubricant. In the preferred embodiment of the invention the polyolefin is polypropylene, the metallocene catalyzed olefinic copolymer is a metallocene catalyzed low density ethylene-octene copolymer, and the lubricant package includes a blend of ethylene bis-stearamide wax as an external lubricant and calcium stearate wax as an internal lubricant. The TPO blend according to the invention also preferably comprises optional antioxidants, UV stabilizers, and colorants.
