ABSTRACT:
Laminated scrap produced by a reaction injection molding process, comprising a thermoplastic resin substrate and a vinyl skin, together with a polyurethane foam layer disposed therebetween, is ground with cryogenic coating. Thereafter, the granulated particles of the scrap lamination are passed serially through density-based separators to separate the laminated layers. The method and apparatus of the invention permit the separation of the layers of such scrap parts, such that one or more of the constituent parts may be recovered.
