The method of extruding porous polyethylene is aimed at obtaining sections. Characterized in that: The extrusion temperature distribution along the length of the plasticising assembly of the extruding device ensures that the extrusion temperature does not fall below 175 degrees C in the section equal to at least three diameters of the worm located inside in the plasticising assembly, in the second part of its length, as measured from the plastic container in the direction of the extruding head.
