Orientierte polymerische mikroporöse Folien |
摘要 |
<p>Polyolefin resin compositions and oriented microporous films prepared from same comprising an ethylene-propylene block copolymer having an ethylene content of about 10 to about 50 wt%, a propylene homopolymer or random propylene copolymer having up to about 10 wt% of a comonomer of ethylene or an alpha -olefin of 4 to 8 carbon atoms, and components selected from a low molecular weight polypropylene, a beta-spherulite nucleating agent and an inorganic filler, and to processes for forming such films wherein the microporous films have improved breathability, strength, toughness and break elongation.</p> |
