Microporous membranes of ultrahigh molecular weight polyethylene |
| abstract |
Microporous membranes and methods of producing such membranes are provided from ultra-high molecular weight polyethylene. The process involves extruding a solution of ultra-high molecular weight polyethylene and a porogen through a stamping die, followed by thermal separation of the polymer and porogen phases. Microporous structures form upon removal of the porogen. The microporous membranes produced include membranes with good air and water permeability, making them particularly useful as filter media and aerated water-resistant membranes. |
