Method for separating and recovering layered plastics joined at an interface

Abstract From the Canadian patent

Abstract of the Disclosure, A process of separating vinyl skin from a foam backing and recovering the separated components by granulating the plastics composite into small chips mixing the chips with a quantity of water in a vessel to swell and break the cell structure of the foam at the foam/vinyl interface resulting in flotation of the foam bits and sinking of the heavier vinyl bits. The separated foam is recovered by adding additional water to flow the foam material from the mix vessel. The vinyl is then removed from the bottom of the vessel and the separated components are dried for recycling or improved disposal purposes.
