Abstract
Rigid polyurethane foams are made using a mixture of polyols that includes 4 to 33% by weight of triisopropanolamine. The mixture of polyols is reacted with an aromatic polyisocyanate in the presence of a blowing agent, a foam-stabilizing surfactant and a urethane catalyst to produce the foam. The foams are useful as thermal insulation layers in multilayer thermal insulation assemblies such as appliance cabinets and walls for industrial and commercial freezers and refrigerators.
