986.012 Title: COMPOSITION AND METHOD FOR PREPARING FOAMS OF SOLID LIQUESCENT MATERIALS USING SELECTED SOLID PARTICULATE SUBSTANCES Inventor: John A. Heinen ABSTRACT OF THE DISCLOSURE Rigid forms are produced from normally solid but liquescent materials by incorporating certain selected solid particulate substances in solid liquescent material either alone or in combination with conventional blowing agents. The solid particulate substance is one which acts as a carrier for an entity which will function as a blowing agent when the material is in the liquid state but which will not be released from the solid particulate substance under normal storage conditions. The solid particulate substance does not undergo physical or chemical change itself to produce a foaming action. Properties of the foam or cellular structure produced by incorporating solid particulate substances may be varied, by utilizing various particulates, sizes, quantities and procedures, above and beyond those achieved, to impart additional characteristics such as structural strength, surface texture, color, insulative properties, skid resistance and the like. The composition and method according to the invention have particularly advantageous application in the production of sulfur foams and cellular aggregates produced by adding fluid coke or anthracite coal as the solid particulate substance to molten powdered elemental sulfur. -2-
