Abstract

Foam reactants are mixed in a mixer head 1 and delivered into a trough 5. In the trough 5 the liquid foam reactants react to produce a creamy liquid that spills over an overflow outlet onto a fall plate 26 leading to a conveyor on which the reaction is completed to form slabstock polymeric foam. A rear wall 22 of the trough 5 is hingedly mounted and ajusted to vary the volume of the trough 5. In this way, the residence time in the trough 5 is adjusted to achieve the desired consistency of liquid spilling onto the fall plate 25. A premixture of air, water and a silicone surfacant may be prepared prior to injection into other foam reactants. This results in consistency of air bubble size with optimum cell formation in the polymeric foam block.
