    摘要: The invention comprises a multi-layer thermoplastic foam sheet comprising a thermoplastic foam layer adjacent to at least one multi-resin layer, preferably comprising a reclaim material mixture recycled from the sheet manufacturing process, and which comprises a thermoplastic barrier resin. In a preferred embodiment, the multi-layer sheet of the invention comprises a four major layer sheet comprising a barrier film layer which comprises a thermoplastic oxygen barrier resin; an inner mutli-resin reclaim layer comprising the oxygen barrier resin used in the barrier film layer; a foam core layer adjacent to the inner multi-resin reclaim layer; and an outer multi-resin reclaim layer, also comprising the oxygen barrier resin, as the other outer layer of the multi-layer sheet. In a more preferred embodiment, impact polystyrene is added to the reclaim layers and polystyrene is used in the foam core to produce multi-layer sheets having an impact-resisting outer layer and a lightweight inner foam core layer, respectively.

    摘要: Laminate suitable for use as automobile trim panel or headliner comprising the following layers: (1) polypropylene fabric, (2) a solid layer comprising a physical mixture of a copolymer of styrene and maleic anhydride, preferably a rubber modified copolymer, and polypropylene and (3) a foam of a copolymer of styrene and maleic anhydride. The laminates can be shaped by thermoforming. Optionally the laminate can contain, on the foam side opposite the fabric, a sheet or film of a rubber modified copolymer of styrene and maleic anhydride.
