Title:
A polypropylene resin composition of an ethylene propylene block copolymer base excellent in shock intensity, a surface property, and mobility
Document Type and Number:
Japanese Patent JP5954931
Kind Code:
B2
Abstract:
An ethylene-propylene block copolymer-based polypropylene resin composition is provided. The ethylene-propylene block copolymer-based polypropylene resin composition contains highly crystalline homo polypropylene (A), ethylene propylene elastomeric copolymer (B) and an optional nucleating agent (C). Since the composition is provided with high impact strength, surface properties and flowability, therefore, the ethylene-propylene block copolymer-based polypropylene resin composition can be applied to large-scale products and thin-wall products.
