Abstract

Process for the extrusion of an expandable plastic composition with a view to obtaining foam internal profiles, rigid, semi-rigid or flexible, having a constant external cross section and which can have a smooth surface, by extruding said composition of expandable plastic material, in the fully expanded state through a row defining an extrusion axis followed by a former substantially aligned with said extrusion axis and defining an elongated forming space having an entrance in the substantially immediate vicinity of said row, and an exit whose straight section is identical to that of the desired profile, characterized by the fact that said material is extruded through a row section whose straight section is substantially the same as that of the desired profile, leaving a hollow space inside the extruded material through the row, and because then it is forced to the material thus extruded to pass through said space of elongated conformation, whose entrance presents a straight section substantially equal to that of the row, and whose exit presents a straight section identical to that of the desired profile, said space being maintained externally at a lower temperature to the point of gelation of the extruded expandable composition, the parameters of the extrusion constituted by the formulation of the composition of matter to be extruded being determined with respect to the expansion properties of the latter, to the conditions of the extrusion, the section of the internal vacuum in the material in course of expansion and the length and the profile of the conformation space in function of each other so that, during the passage of the extruded material through said space, said material undergoes its expansion towards the interior of the profile filling at least partially the internal vacuum in the latter.
