  • Publication number: 20210347989
    Abstract: A rigid polyurethane foam formulation comprising a polyol composition comprising, by weight based on the weight of the polyol composition, more than 70% of at least one polyester polyol having an average hydroxyl number of from 150 to less than 300 mg KOH/g and an average functionality of at least 2; a blowing agent comprising water and an auxiliary blowing agent; a silicone copolymer surfactant; from 1% to 5% by weight based on the weight of the polyol composition, of a cyclic siloxane having a surface tension less than 21 dynes/cm at 25° C., wherein the weight ratio of the cyclic siloxane to the silicone copolymer surfactant is from 0.6 to less than 2.27; a catalyst, and optionally a flame retardant; and a polyisocyanate; such that the isocyanate index is in the range of from 180 to 500; a rigid polyurethane foam formed from the foam formulation; and a method of forming a rigid polyurethane foam.

  • Patent number: 10125235
    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.
