发明名称 Method Of Producing A Silicone Rubber Item And The Product Obtainable By The Method
摘要 A method of producing a silicone rubber item. The method includes the steps of i) shaping the silicone rubber item and ii) subjecting the shaped item to a cold curing, wherein the cold curing includes feeding the shaped item into a reactor, and subjecting the shaped item to an extraction treatment using carbon dioxide containing solvent at a pressure between 10 and 50 bars, wherein the item has an initial temperature below 60° C. in the extraction step, and in at least a part of the extraction time the item has a temperature below 25° C. and a pressure so that the carbon dioxide is in its liquid state. The reactor may preferably be rotated during the cold curing
