ABSTRACT:
A molded protective strip for automobiles is prepared by the gas injection molding of a resin composition which comprises (A) 55 to 75% by weight of polypropylene, (B) 18 to 30% by weight of ethylene-propylene copolymer rubber, and (C) 10 to 20% by weight of talc, has a ratio (MI).sub.PP /(MI).sub.EPR of 10 or less, and a polydispersity index of 20 to 100. (MI).sub.PP and (MI).sub.EPR represents melt indices of the polypropylene of component (A) and the ethylene-propylene copolymer rubber of component (B), respectively. The polydispersity index is calculated from a frequency-storage modulus curve obtained with a composition consisting of components (A), (B), and (C) alone at the temperature of 230.degree. C. The molded protective strip can be prepared without using a vinyl chloride resin, shows almost no heat shrinkage, has a small coefficient of linear expansion, is excellent in dimensional stability, and exhibits excellent appearance.
