    摘要: The present invention is to a process of producing a molded rigid polyurethane foam for application in appliance, having a reduced thermal conductivity at densities between 33 and 38 kg/m 3 . The molded rigid polyurethane foam have a ratio of applied foam density (kg/m 3 ) to lambda (mW/mK), measured at 10°C, 24 hours after foam production from 1.65 and to 2.15 and are obtained by the process of injecting into a closed mold cavity under reduced pressure a reaction mixture at a packing factor of 1.1 to 1.9 and the reaction mixture comprises:
    A) an organic polyisocyanate;
    B) a physical blowing agent;
    C) a polyol composition containing at least one polyol with a functionality of 3 or greater and a hydroxyl number between 200 and 800 and a water content of 0 to 2.5 weight percent of the total polyol composition;
    D) catalyst; and
    E) auxiliary substances and/or additives.

    摘要: A storage stable isocyanate-reactive composition has ethylene oxide content from 1 wt% to 50 wt%, based on the total weight of an isocyanate-reactive component that includes a polyol component, a catalyst component, and a blowing agent component. The polyol component includes at least one polyol, the catalyst component includes at least one amine catalyst, and the blowing agent component includes at least one hydrohaloolefin based blowing agent. The isocyanate-reactive component is storable at least at one of room temperature and a higher temperature for a period of at least 1 day with a less than 10 second change in gel time when reacted with an isocyanate component at an isocyanate index from 100 to 150, compared to when the same isocyanate-reactive component is stored for a period of less than 1 day at room temperature and reacted with the same isocyanate component at the same isocyanate index from 100 to 150.
