Abstract: Comminuted melamine-formaldehyde condensate foam or fiber material (I) is used to produce hard polyurethane foams with reduced thermal conductivity. Independent claims are also included for the following: (1) a process for producing hard polyurethane foams with reduced thermal conductivity by reacting polyisocyanates with at least one compound containing at least two reactive hydrogen atoms in the presence of water or other blowing agents and other additives, in which (I) is added to the reaction mixture; (2) a hard polyurethane foam produced by a process as in (1).

Abstract: Open-cell melamine resin foam (MF foam) in which the surface of the cellular structure is completely or partly coated with an ammonium salt. Independent claims are also included for: (a) a method for the production of this MF foam by coating, spraying or impregnating the foam with an aqueous solution of ammonium salt, optionally squeezing out excess liquid and drying the foam; (b) open-cell MF foam with a fire rating of Class A in the NT fire 004 test.
