In for type foam produced in (expanded) PVC, including the step of heating the ingot (13) of the polymer mixture in the closed mold process, the step of: (a) defined by the mold 10, the closed in an environment having a fixed volume, the microcell 20 in the hot-molding (hot molding) step of the process controlling the firing of said mass (13) due to the control, the mass (13) within the foaming gas (blowing gas) the under the action of the pressure produced by the formation and foaming, the more fine particles 16 is the polymer mixture of compressible material adapted to be retracted to its initial form type (B) having a smaller volume in (a) with a large volume of of the mass obtained by Jim as present in (13); And (b) the density of the fine particles contained in the lump of the molded foam material (16) with a larger volume in the form of (B) expansion step to the initial form (A), this taken along the foamed material is a foamed determined in a lump (13c) of the material by the simultaneous presence of the fine particles 16 microcell type (a) has a larger volume and 20 of the foaming gas, the process comprising: a. In relation to the prior art for the production of a foamed plastic material, during the process of the present invention the molding process, even with the much lower than that of the blowing agent used in the present process of this type as well as to prevent the formation of the melt loss you can get a PVC foam with the desired density value.
