<p>The method comprises forming an expandable thermoset plastic comprising 20-40 wt.% of a flame retardant, cutting the foamed thermoset plastic into small pieces, homogeneously mixing the small pieces with 60-80 wt.% of pre-expanded polystyrene particles to obtain a mixture, introducing the mixture into a mold, and forming a composite body by introducing pressure and/or heat. The pre-expanded polystyrene particles are embedded in a surface of the foamed thermosetting resin. The foamed thermoset plastic is homogeneously mixed with other pre-expanded polystyrene particles.

The pre-expanded polystyrene particles are embedded in a surface of the foamed thermosetting resin. The foamed thermoset plastic is homogeneously mixed with other pre-expanded polystyrene particles. The expandable thermoset plastic is present in the form of square or round pieces with a maximum edge length or a maximum diameter of 1 mm, and is cut to 6 mm in length, and has a bulk density of 20-100 kg/m 3>. The mixture is present in the form of fibers, fillers and/or additives before introducing into a vessel.</p> |
