A process for the production of porous silicone moldings

The invention relates to a process for producing thin porous molded body of silicone compound S, wherein in a first step a solution or suspension of silicone compound S or output silicone compound SA in a mixture of solvents L1 and L2 solvent is formed, in a second step, the solution or suspension is placed in a mold, S is removed in a third step solvent L1 from the solution or suspension to the solubility of the silicone compound is not reached in the mixture of solvent S1 and solvent L2, wherein a rich silicone compound S A phase and a poor on silicone compound S phase B forms and structure formation takes place through the phase A and the solvent L2 and L1 residues of the solvent are removed in a fourth step, wherein, if the silicone compound S is formed from starting silicone compound SA, this is done in one or more steps selected from the first, second and third step. Also subject of the invention, the molded body obtainable by the process and their use.
