Abstract

Process for the extrusion of thermoplastic materials, to form an article of expanded plastic material comprising an expanded internal structure and a non-expanded skin formed of said plastic material and molecularly bound to said expanded structure of the article, characterized in that it is made passing a plastic material in a molten state, containing an expanding agent in an extrusion die keeping the hot mixture under pressure, extrude the mixture into a die orifice in which the pressure is lowered to cause an expansion of the extruded article and immediately after this extrusion phase at least one surface of the article is cooled to prevent its expansion.
