Abstract
The invention relates to a method for producing a flat porous product, in which a solution of an elastomeric material is deposited on a temporary substrate and the elastomeric material is coagulated on the substrate from the solution with the aid of a nonsolvent, wherein the surface of the substrate has an adhesion to the coagulating elastomer which is such that, after coagulation, the elastomeric flat product can be removed from the substrate without damage and the side (macroporous zone or bottom layer) of the elastomeric flat product facing the substrate possesses pores having a diameter in the region of 20-200 .mu.m and has a porosity of more than 75%, a flat product which can be obtained according to this method for use as wound covering material and a method for treating wounds therewith.
