HEAT-RESISTANT POLYOLEFIN RESIN COMPOSITION AND RESIN MOLDING

摘要

PURPOSE:To obtain the title composition excellent in thermal aging resistance and heat-resistant rigidity by adding a specified amount of a reinforcing fiber to a resin component comprising an ethylene- or propylene-based polyolefin and a polyphenylene sulfide. CONSTITUTION:10-60 pts.wt. reinforcing fiber (e.g. glass fiber) is added to 100 pts.wt. resin component comprising 78-90wt.% ethylene- or propylene-based polyolefin (e.g. PE or maleic anhydride-grafted PE) and 10-22wt.% polyphenylene sulfide desirably of a melt viscosity of 50-50000P at 300 deg.C and a shear rate of 200/sec.
