Title: Michael Brehm: Innovator in Polyurethane Foam Technology
Introduction
Michael Brehm is a notable inventor based in Weinheim, Germany. He has made significant contributions to the field of polyurethane foam technology, holding 2 patents that showcase his innovative approaches.
Latest Patents
One of his latest patents is titled "Method for matched die molding a fiber reinforced polyurethane foam." This invention involves positioning a fiber reinforcement on the female part of a matched die. A reactive foaming mixture of polyol and isocyanate is then placed on the reinforcement. The male part of the die set is closed on the female part to compress the reinforcement while the mixture's foaming reaction occurs. This method allows for finer individual fiber thicknesses and ensures that the foam produced fills all voids between the fibers. The addition of a neutral ester enhances the foaming process, resulting in better penetration of the foam throughout the reinforcement.
Another significant patent is "Rinsing multi component foam machines." This invention improves the production process of polyurethane foam by introducing a rinsing agent during the machine's cleaning phase. The method involves supplying two or more components to a machine, mixing them, and then extruding the mixture to form a foaming mass. After discontinuing the supply and extrusion, the machine is rinsed with a specific rinsing agent before resuming the process.
