Stretched-filled microporous films and methods of making the same |
摘要 |
<p>A breathable microporous film is prepared by extruding a film comprising about 30 to 70% by weight of a thermoplastic polymer, about 30 to 70% by weight of filler particles having an average particle size less than about 10 microns and about 100 to 1000 PPM of a mono-functional hindered phenol, such as alpha -tocopherol, and then sufficiently stretching the filled film in at least one direction thereby creating a fine pore network therein and a water vapor transmission rate in excess of 300 g/m2/24 hours.</p> |
