  • Laminates for making electroconductive fuel tubes
    Patent number: 6723400
    Abstract: An electroconductive, multilayered hollow molding comprising at least two thermoplastic resin layers, in which at least one layer is a layer of (a) a thermoplastic resin composition consisting essentially of a polyphenylene sulfide resin; one layer is a layer of (b) a thermoplastic resin composition consisting essentially of a thermoplastic resin other than a polyphenylene sulfide resin; and at least one of the layers is a layer of an electroconductive, thermoplastic resin composition comprising an electroconductive filler and/or an electroconductive polymer, and a thermoplastic resin.

  • Laminate containing a layer composed of polyphenylene sulfide blended with other polymers
    Patent number: 6485806
    Abstract: Multilayered moldings, which comprise a laminate structure of (A) a layer of a polyphenylene sulfide resin (hereinafter referred to as PPS resin) composition and (B) a layer of a thermoplastic resin except PPS resins and which are characterized in that the PPS resin composition constituting the layer (A) comprises (A1) 100 parts by weight of a PPS resin, (A2) from 1 to 80 parts by weight of a thermoplastic resin having at least one functional group selected from epoxy groups, acid anhydride groups, carboxyl group and its salts, and carboxylate groups, and (A3) from 5 to 80 parts by weight of a thermoplastic resin that is similar in kind to the thermoplastic resin constituting the layer (B), have good hot water resistance, antifreeze resistance, chemical resistance, heat resistance, abrasion resistance, gas permeation resistance and interlayer adhesion.
