摘要： A cutting and packaging process for expanded polystyrene foam blocks having an original geometric, as well as a product, is provided. The process internally cuts the expanded polystyrene foam blocks to provide pre-cut expanded polystyrene foam blocks. The pre-cut expanded polystyrene foam blocks are maintained in their original geometric form and are packaged in this original geometric form to prevent disassembly of said pre-cut expanded polystyrene foam blocks.

摘要： A closed circuit process for the production of expanded polystyrene foam is described, comprising the steps of: (a) pre-expanding raw polystyrene beads containing a blowing agent in a pre-expansion vessel; (b) storing the beads in one or more closed storage containers to allow the expanded beads to return to substantially atmospheric pressure; (c) molding the expanded beads to a desired configuration in a closed mold with steam; and (d) removing the thus-formed article from the mold and placing such in an aging room, wherein at each stage the blowing agent released from the beads is recovered, separated from any residual steam by means of a condensing system, and introduced into the burner of a steam generator, thereby serving as fuel for the process.
