Abstract

Separators are manufactured by a paper-making method, sometimes followed by partial melting, from an aqueous dispersion comprising a blend of cellulosic fibers and olefin polymer fibrils in a ratio of from 20:80 to 40 to 60, the blend having a degree of freeness of from 40 to 75 DEG SR. The blend also contains: from 20 to 55% of an inorganic powder -substantially insoluble in sulphuric acid from 0.01 to 0.3% of an ionic or non-ionic wetting agent up to 50%, preferably from 10 to 20% of glass fibres and up to 50%, preferably from 10 to 20% of a vinyl or like polymer latex.
