Abstract:
Polyurethane foam-forming compositions, methods of producing polyurethane foams, polyurethane foams produced from such compositions made by such methods, as well as isocyanate-reactive compositions. The polyurethane foam-forming compositions include a polyol blend, a blowing agent composition, and a polyisocyanate. The polyol blend includes an aromatic amine-initiated polyether polyol, a saccharide-initiated polyether polyol, and an aromatic polyester polyol and has a content of —C2H4O— units of 3 to 6% by weight, based on the total weight of the polyurethane foam-forming composition. The blowing agent composition includes a hydrochlorofluoroolefin and a carbon dioxide-generating chemical blowing agent.
