Abstract (en)
[origin: US4769395A] The invention proposes a polyurethane assembly foam which is produced by foaming a mixture in which, before the completed foaming, there are brought together a solution of the propellant of the foam, a prepolymer of polyurethane, a reaction resin and, if need be, parts of its reagent with components kept separate from the solution until the final foaming, namely the reagent or individual ones of its components as well as possibly hardening accelerators of the polyurethane. The apparatus includes an outer pressure tank for the reception of the solution and an inner pressure tank for the separation of the components of the solution and a ram, movable from outside for perforating the inner pressure tank and permitting mixing of the contents of the tanks prior to release of the solution.
