Abstract

L'invenzione riguarda un nuovo procedimento di riciclaggio, mediante il quale materiali plastici termoindurenti non rinforzati da fibre vengono trasformati di nuovo in masse per stampaggio termoindurenti e possono essere di nuovo stampati per dare oggetti nuovi di materiale plastico secondo il procedimento di stampaggio ad iniezione o secondo il procedimento di stampaggio a compressione.The invention relates to a new recycling process, by which thermosetting plastic materials not reinforced by fibers are transformed again into thermosetting molding masses and can be molded again to give new objects of plastic material according to the injection molding process or according to the compression molding process.
