Polypropylene resin composition having excellent transparency stress-whitening resistance and impact resistance for thermoforming applications

摘要

TECHNICAL FIELD The present invention relates to a polypropylene resin composition applicable to vacuum molding, which comprises an ethylene-propylene random copolymer obtained by copolymerizing propylene homopolymer or ethylene in a small amount and ethylene-propylene random copolymer obtained by stepwise polymerization of ethylene- To a polypropylene resin composition. More specifically, the present invention relates to an ethylene-propylene block copolymer which has an ethylene content, a content of a rubber copolymer and a melt index of each component, and is excellent in impact resistance including an organic nucleating agent, To a polypropylene resin composition for molding.
