Abstract
This invention relates to a thermoplastic resin composition containing: (a) about 85 to about 95 weight % of a crystalline propylene ethylene block copolymer or a combination of crystalline propylene ethylene copolymer and a propylene homopolymer whose (i) ethylene content ranges from about 2.2 to about 4.2 weight %, (ii) melt flow rate ranges from about 20 to about 30 g/10 minutes, and (iii) isotactic/pentad fraction of propylene homopolymer is greater than or equal to about 94%; (b) about 2 to about 8 weight % ethylene butene rubber whose melt flow rate ranges from about 6 to about 8 g/10 minutes and density ranges from about 0.860 to about 0.865 g/cc and (c) about 2 to about 8 parts by weight talc with an average diameter ranging from about 1 to about 2 &mgr;m. The thermoplastic resin composition is lightweight but maintains good rigidity and heat resistance properties. The thermoplastic resin may be molded into an article, such as those used as parts for an automobile interior.
