Propylene based polymer composition

Abstract

Abstract PURPOSE:To obtain the titled composition, having excellent heat resistance, continuously usable at >=50 deg.C temperature and suitable as automotive parts, such as air cleaner cases, or parts of lighting equipment, by blending a specific amount of carbon black having a specific particle diameter. CONSTITUTION:A composition obtained by blending 100pts.wt. propylene based polymer having 1-100g/10min melt flow index with 0.05-5pts.wt., preferably 0.1-3pts.wt. carbon black having 50-750mum particle diameter prepared by granulating acetylene black having 20-200mum average particle diameter. Furthermore, an inorganic filler, rubber and ethylenic polymer are preferably blended.
