Abstract: Provided is a rubber laminated resin composite comprising a polyamide-based resin molded product and rubber that is vulcanization bonded to the polyamide-based resin molded product; the polyamide-based resin molded product being molded from a polyamide-based resin that is blended with 0 to 70 wt. % of a filler based on the total amount of the filler and the polyamide-based resin, and that comprises an aliphatic amine compound having an amine equivalent of 950 or less in an amount of 0.045 mmol or more, preferably 0.050 to 2.0 mmol, more preferably 0.065 to 1.5 mmol, per g of the polyamide-based resin. The rubber laminated resin composite is produced by molding a polyamide-based resin that is blended or not blended with a filler, after the addition of an aliphatic amine compound thereto, and then vulcanization bonding of fluororubber or acrylic rubber to the obtained polyamide-based resin molded product.

Abstract: A nitrile rubber composition comprising 5 to 50 parts by weight of carbon black, 5 to 60 parts by weight of graphite having an average particle diameter of 5 ?m or less, 5 to 50 parts by weight of conductive carbon other than these carbon black and graphite, and 0.5 to 3.5 parts by weight of 2,5-di-tert-butylhydroquinone or 2,5-di-tert-amylhydroquinone as an antioxidant, based on 100 parts by weight of nitrile rubber. The nitrile rubber composition can yield a vulcanization molded product, besides maintaining characteristics as a conductive material, satisfying muddy water resistance, sealing properties, and low torque characteristics required for rolling bearing oil seals for vehicles, etc., and having a rubber volume change kept low when the product is washed with water after exposure to an antifreezing agent.
