Abstract

A method for the production of reconstituted expanded polystyrene, which comprises mechanically disintegrating previously formed expanded polystyrene into particles that retain their expanded character, applying a small amount of a solvent, swelling or plasticizing agent for the polystyrene to the surface of the particles and subjecting a mass of particles thus treated under pressure until they adhere to each other to form a coherent shaped body, but retaining their essentially expanded condition, finally cutting the material resulting from the treatment into sheets or molding it under pressure forming a sheet or panel.
