PERFORATIONSBESTÄNDIGE POLYOLEFINMEMBRANEN |
| 摘要 |
<p>Briefly, in one aspect, the present invention provides puncture resistant microporous materials made of melt-processable semi-crystalline thermoplastic polymers. The microporous materials can be produced at relatively high rates and at low cost. Films and multilayer constructions made of the microporous materials and methods of making microporous materials also are provided.</p> |
