    Abstract: 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.

    Abstract: The presently disclosed technology provides a composition and method for producing a thermally stable, rigid polyurethane and/or polyisocyanurate foam by reducing or eliminating the presence of alkali metal components and/or alkali earth metal components, thereby producing a foam, which under fire conditions, will at least maintain its volume or intumesce or not reduce its volume by more than about 30%. The presently disclosed technology allows for a reduction in alkali and/or alkali earth metal components in foams that meet current standards with reduced fire retardant loadings. The presently disclosed technology further provides foams with lower alkali and/or alkali earth metal components which may be made to increase in volume under fire conditions.
