Abstract

The invention relates to a process for the manufacture of urea formaldehyde foams of the type used in mining or tunnel construction. The process comprises: (a) mixing a solution of urea formaldehyde resin with a foaming agent; and (b) curing the mixture; characterized in that, from 3 to 12% by weight of the total composition of urea is added to the urea formaldehyde resin or the foaming agent or both immediately prior to the mixing of the components in step (a).
