ABSTRACT:
These novel molds are characterized in that they contain a cavity in porous material which is not monolithic, but which, on the contrary, is constituted by zones B with high capillary forces and by zones A with low capillary forces for liquids. The process of using these novel molds is useful for the manufacture of expanded plastics articles.
