Abstract

The invention concerns a process for reclaiming foam off-cuts and/or waste foam by: (a) mechanically chopping the foam off-cuts and/or waste to a particle size of smaller than or equal to 10 mm; (b) mixing the foam off-cuts and/or waste with a liquid, foaming, one-part prepolymer; (c) removing excess, non-wetting prepolymer where necessary; (d) stirring in water while homogenising the mixture; and (e) foaming to the desired shape.
