  • Patent number: 11945141
    Abstract: The invention relates to a method for the production of foamed areal polyurethane(PUR)/polyisocyanurate(PIR) moldings, where a polyurethane/polyisocyanurate reaction mixture is injected into a mold that is under elevated pressure and then a depressurization takes place, and the foaming process is thus induced, and after the reaction the molding is demolded, and to a mold for carrying out the method.

  • Publication number: 20220297358
    Abstract: A distributor bar for applying a liquid reaction mixture to a cover layer, comprising a distribution channel and multiple exit openings, the geometry of the exit openings in the distributor bar being chosen such that the discharged quantity at at least one end of the distributor tube is higher than in the center of the distributor bar. An application device containing the latter and a method for producing foam composite elements using this distributor bar are also provided.
