  • Patent number: 5801205
    Abstract: Provided are a reprocessed resin which decreases volume of a thermoset resin foamed material recovered from waste of various resin products and moldably form said thermoset resin foamed material into various molded articles to thereby effectively recover and reprocess the thermoset resin foamed material, a reprocessing method therefor and a method for molding a molded article formed of said reprocessed resin. A pulverized resin to be processed formed of a thermoset resin foamed material along with a thermoplastic resin molding material are applied with a stirring impact force to produce shearing heat generation based on the stirring impact force and are gelled and blended by the shearing heat generation. In this process, the thermoplastic resin molding material is adhered so as to cover the whole surface of the individual pulverized resin to be processed and cooled and granulated to have 15 mm or less of particle diameter to thereby decrease volume by 0.
