Composition of polypropylene resin

摘要

The present invention relates to a polypropylene resin composition comprising an ethylene-propylene copolymer having low molecular weight and an ethylene-propylene copolymer having high molecular weight but both have different constant melt flow rates. This polypropylene resin composition exhibits excellent physical properties such as impact resistance, heat resistance (thermal deformation resistance) and scratch resistance and thus, it can be substitutable for conventional ABS/PC resins and improve reclamation of automotive plastic parts such as housing assembly glove box parts due to deletion of coating process.
