<p>A conductive sheet, having three layers laminated together by co-extrusion, comprises one substrate layer and two surface layers, wherein the surface layers, each containing carbon black and acting as conductive layers, are made from polyester and/or copolyester and acrylonitrile-butadiene-styrene and/or polystyrene and have a surface resistance of not more than 10<SP>8</SP> ohms. The melt flow index of the material for the conductive layers during the extrusion step is not less than 5.0 g/min (loading, 10 Kg; temperature, 250 {C). The surface layers also contain a compatibiliser and a toughening agent. The substrate layer is made from polyester and/or copolyester and/or acrylonitrile-butadiene-styrene and/or polystyrene. The sheet is useful for the packaging of IC products and parts.</p> |
