VERFAHREN ZUR HERSTELLUNG VON MIKROPOROESEN FOLIENMATERIALIEN

摘要

Microporous membrane materials suitable for electrolytic cell utilization are formed from the blend of particulate polytetrafluoroethylene, a dry pore forming particulate material, and an organic lubricant. The materials are milled and formed into a sheet, which is rolled to the desired thickness, sintered, and subjected to leaching of the pore forming materials.
