Title: COMPOSITE MATERIAL COMPRISING POLYSTYRENE RESIN FOAM LAYER AND THERMOPLASTIC RESIN LAYER
Abstract:
A composite material comprising a polystyrene resin foam layer, an alloy layer on at least one side of the polystyrene resin foam layer and a thermoplastic resin layer on the alloy layer, wherein the thermoplastic resin layer comprises a resin selected from a polyolefin resin and a polyester resin, the alloy layer comprises a mixture of a polystyrene resin with a thermoplastic resin selected from a polyolefin resin and a polyester resin, with the proviso that the thermoplastic resin in the alloy layer is a polyolefin resin when the thermoplastic resin layer consists substantially of a polyolefin resin, and the thermoplastic resin in the alloy layer is a polyester resin when the thermoplastic resin layer consists substantially of a polyester resin, and wherein the adhesion strength between the polystyrene resin foam layer and the thermoplastic resin layer is 980 mN/25mm or more.
