Abstract

Process for preparing shaped porous bodies of synthetic thermoplastic substances, characterized in that it consists of introducing into particles of thermoplastic synthetic substance, kept in aqueous suspension, at least one blowing agent, which is gaseous at 15º C and at atmospheric pressure, constituted by a hydrocarbon chlorofluorinated or by a mixture of chlorofluorinated hydrocarbons, said solvent expanding agent of the synthetic thermoplastic substance, fully expanding by heating said particles by heating such hot particles, and heating said expanded particles, inside forming molds substantially filled therewith. particles, said molds being provided with orifices for the entrance of the heating fluid, in order to obtain expanded porous bodies with low bulk density.
