POLYPROPYLENE RESIN COMPOSITION FOR EXTRUSION BLOW MOLDING

摘要

Provided is a polypropylene resin composition for extrusion blow molding, which has more excellent melt strength and elongation viscosity than the conventional resins, high heat resistance, and a good gas barrier property. The polypropylene resin composition for extrusion blow molding comprises 0.1-1.0 parts by weight of an antioxidant and 1-20 parts by weight of a blowing agent based on 100 parts by weight of a base resin composition including 30-99wt% of polypropylene having a long chain and 1-70wt% of propylene-ethylene random copolymer having an ethylene content of 1-4mol%. The polypropylene resin composition has a melt strength of 100mN or more.
