Abstract
A water-blown polyurethane foam is provided between two substrates in foamed-in-place applications such as cooling containers. The water-blown polyurethane foam is made dimensionally stable at low densities by adding lithium salts of a 2 to 24 carbon atom carboxylic acid to the polyol component. The dimensional stability of the foam at the low densities further results in raw material savings.
