发明名称 Use of comminuted melamine-formaldehyde condensate foam or fiber material to produce hard polyurethane foams with reduced thermal conductivity
摘要 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).
