    Abstract: The invention relates to a method for producing thin porous membranes made of cross-linkable silicone compositions (S), according to which method an emulsion is formed from the silicone compositions (S) using a pore forming agent (P) in the presence of an emulsifier (E) and optionally solvent (L) in a first step, the emulsion is given a form and the solvent (L), if present, is allowed to evaporate in a second step, the emulsion is cross-linked in a third step, and the pore forming agent (P) is removed from the cross-linked membrane in a fourth step. The invention further relates to membranes that can be produced according to the method and to the use thereof for separating mixtures, in adhesive plasters, as a water-repellent and breathable layer in textiles or as packaging materials.

    Abstract translation: 本发明涉及一种用于生产由可交联硅氧烷组合物(S)制成的薄多孔膜的方法,根据该方法,使用成孔剂(P)在有机硅组合物(S) 乳化剂(E)和任选的溶剂(L)在第一步骤中,乳液得到形式,并且在第二步中使溶剂(L)(如果存在)被蒸发,则乳液在第三步中交联 在第四步骤中,从交联膜除去成孔剂(P)。 本发明还涉及根据本发明的方法生产的膜以及其在粘合剂膏剂中分离作为纺织品或包装材料中的防水透气层的混合物的用途。
