Abstract

A process and device for continuously producing homogeneous, fine-pored, aq. and/or water/alcohol based, synthetic resin foam, comprises a foaming chamber (3) into which resin (1) and compressed air (2) are pumped, a cycling hose (4) and a combined catalyst injection and mixing chamber (5), followed by supplementary mixing chambers for the carrier foam and additives, in which there are no baffles, worms or other agitators.
