Abstract
Disclosed are HCFO-containing isocyanate-reactive compositions, polyurethane foam-forming compositions containing such isocyanate-reactive compositions, rigid polyurethane foams made using such polyurethane foam-forming compositions, and methods for producing such foams, including use of such foams as insulation in the construction of refrigerated storage devices. The isocyanate-reactive composition can exhibit a long shelf life, be shelf-stable, and produce a foam with good thermal insulation properties.
