Document Type and Number:
Japanese Patent JP2021075709
Kind Code:
A
Abstract:
To provide a soft polyolefin resin composition excellent in insulation characteristics, thermal resistance and mechanical properties.SOLUTION: A polyolefin resin composition includes: (A) 50 wt.% to 95 wt.% of an ethylene-propylene block copolymer obtained by polymerization of a propylene homopolymer or an ethylene-propylene random copolymer with an ethylene-propylene rubber copolymer in stages in reactors; (B) 4.8 wt.% to 40 wt.% of an ethylene-α-olefin rubber copolymer; and (C) 0.2 wt.% to 10 wt.% of a copolymer of ethylene and a polar monomer.SELECTED DRAWING: None
