Abstract

Procedure for the preparation of profiles of cellular structure, of small volumetric mass, of the type that comprise an internal part of the cellular structure with closed cells and a smooth and shiny skin with a compact structure, characterized in that it is extruded through a row, a thermoplastic polymer composition, containing at least one blowing agent, and at least one finely divided filler; the row being maintained at a temperature lower than the temperature necessary to cause the decomposition of the expansion agent near the surface of the profile in contact with the row and higher than the temperature at which the rubbing of the material on the row, it causes a tearing of said surface and extrusion is carried out so that a partial expansion of said material occurs in the row.
