Abstract

A process for preparing multilayered foam articles such as an automotive seat or a sound/thermal insulation panel is disclosed. A mold is arranged so that the bottom surface of the mold is flat or inclined to the horizontal plane. A first liquid formulation designed to produce an elastomer is poured into the mold from a mixing head onto the seating zone of the mold and pouring a second liquid formulation designed to produce a foam is poured into the mold from the same or different mixing head outlet. The second liquid foam formulation is allowed to spread on top of the first liquid formulation, the mold is closed and the materials are allowed to rise and cure in the mold.
