Abstract

Process for obtaining molded bodies based on thermoplastics of cellular structure by heating thermoplastics of fine particles, cellular structure but still susceptible to further expansion, in closed molds that allow the escape of air, at temperatures above the softening point of the thermoplastics, characterized in that before beginning the heating, the mass of the particles is compressed in certain points of the mold.
