Abstract
A process is disclosed for preparing an open-celled rigid polyurethane foam by reacting an organic polyisocyanate with a polyol in the presence of a blowing agent, a cell opening agent and exfoliating graphite, wherein the thermal conductivity of the foam is from 28 to 35 mw/mk. Such foams are applicable in the construction industry where it is desired to have a foam having flame retardation properties and a low thermal conductivity.
