摘要： A method using a two part process line is proposed for manufacturing foams from polymers or polymer mixtures useful for making molded bodies. The process line is divided into at least one first part and one second part. The polymer or polymer mixture is melted in the first part and a gas at a pressure increased relative to the melt pressure is added with the influence of a shearing and/or kneading device on the melted polymer or polymer mixture enriched with gas. In the second part of the process line, foam is formed from the gas-enriched polymer or polymer mixture at a higher pressure than the pressure in the first part of the process line. Membranes can be made from the molded bodies made by the method described above.

摘要： In a method of producing hollow fiber membranes, wherein a molten polymer charged with a gas under pressure is provided in an extrusion apparatus, the polymer melt including the gas under pressure is extruded from the extrusion apparatus through a hollow fiber-forming extrusion nozzle with a predetermined pressure drop which provides for a concurrent expansion of the gas contained in the polymer melt thereby forming a porous hollow fiber membrane.

摘要： A shaped part having members that are positively interconnected via thermal treatment. The shaped part includes a metallic member having a first flange that is delimited by an outer contour of the metallic member and projects essentially at right angles therefrom. The first flange defines a recess-like opening having a base in which is provided a circumferential groove that extends essentially parallel to the first flange. A second flange is formed between a base of the groove and a contiguous surface of the metallic member. The shaped part also includes a ceramic member that is received in the recess-like opening. Prior to creation of the positive interconnection between the metallic member and the ceramic member, at least the metallic member is heated up.
