A method for producing a microporous membrane comprising the steps of: providing an ultrahigh molecular weight polyethylene (UHMWPE); providing a filler; providing a processing plasticizer; mixing UHMWPE, filler and the processing plasticizer together to form a mixture having a weight ratio of filler to UHMWPE of from 1:9 to 15:1 by weight; extruding the mixture to form a sheet from the mixture; processing said sheet where processing is selected from the group consisting of: calendaring, casting or blowing; extracting all or part of the processing plasticizer from the sheet to produce a matrix comprising UHMWPE and the filler distributed throughout the matrix, to produce a microporous matrix sheet; and optionally calendaring the microporous matrix sheet to produce a microporous membrane. |
