Abstract

A process for the manufacture of a lightweight construction material with cellular structure from a synthetic material, characterized in that the synthetic material is heated and subjected to pressure, mixing a mass of filler to the mass of plastic which, under pressure normal and/or at elevated temperature, adopts at least partially gaseous form, and placing the mixture by mixing organs that rotate at high speed, approximately at homogenization temperature, which is lower than the liquefaction temperature, which is homogenized, and because the temperature of the mixture is controlled in such a way that, during the generation of the gas by the filler, the synthetic material solidifies forming a stable body with cellular structure.
