Patent

CA 2303131

A distinctive technique for making a microporous film includes a stretching of a layer composed of a polymer material and at least about 5 wt.% of a particulate filler material. The particulate filler material has been distinctively treated with an operative amount of surface-active material having a HLB value of not less than about 6. Desirably, the stretching includes a biaxial stretching of the polymer layer.

L'invention concerne une technique caractéristique de fabrication d'un film microporeux, qui comporte une étape d'étirage d'une couche constituée d'une matière polymère et d'au moins 5 % en poids d'une matière de charge particulaire. La matière de charge particulaire a été traitée de manière caractéristique à l'aide d'une quantité active de matière tensioactive qui présente une valeur d'équilibre hydrophile-lipophile non inférieure à environ 6. De préférence, l'étape d'étirage comporte un étirage biaxial de la couche polymère.
