PCT No. PCT/EP93/01633 Sec. 371 Date Dec. 15, 1994 Sec. 102(e) Date Dec. 15, 1994 PCT Filed Jun. 25, 1993 PCT Pub. No. WO94/00288 PCT Pub. Date Jan. 6, 1994.A method for the production of integral skin foam is provided. An inert, non-flammable gas is added together with a low quantity of hydrocarbon fluid to a liquid skeleton substance. Only the inert, non-flammable gas serves during energy supply for foaming up the skeleton substance. The hydrocarbon fluid promotes the formation of a dense outer skin of the integral skin foam. The liquid skeleton substance is brought into a chamber and a sonochemical process is brought about in order to dissolve the gases in the liquid skeleton substance. The hydrocarbon fluid is less than 1% by volume of the inert gas and the liquid skeleton substance. |
