PURPOSE:To provide the titled composition having excellent moldability and excellent impact strength of molded article, and giving little abrasion damage to the molding machine and rolling machine during molding, by compounding a polypropylene resin with zinc powder, metallic powder or metal oxide powder coated with zinc, and a modified polyolefin. CONSTITUTION:The objective composition is obtained by thoroughly kneading (A) 5-50pts.wt., preferably 10-25pts.wt. of a polypropylene resin with (B) 95- 50pts.wt., preferably 90-75pts.wt. of zinc powder and/or metallic powder or metal oxide powder (e.g. powder of iron, iron oxide, etc.) coated with zinc and (C) 1-5pts.wt., preferably 2-4pts.wt., based on 100pts.wt. of (A)+(B), of a modified polyolefin. USE:Suitable for fabrication of the flywheel of a video deck, record player, etc. |
