摘要： A rubber-metal laminated gasket material comprising a metal plate and fluororubber or nitrile rubber laminated on the metal plate, wherein an amorphous carbon film having a nanoindentation hardness on a silicon wafer of 10 GPa or more and a film thickness of 200 nm or more is formed on a rubber layer outer surface of the rubber-metal laminated gasket material by a plasma CVD method that supplies a high-frequency power from a high-frequency power source using unsaturated hydrocarbon gas. The rubber-metal laminated gasket material reduces the wear and abrasion of the gasket material due to friction with the seal mating surface under high temperature use.

摘要： A resin-rubber composite in which a polyamide-based resin-molded product or a polyphenylene sulfide-based resin-molded product is directly vulcanization-bonded to a peroxide-crosslinkable nonpolar rubber composition, which forms a rubber layer, without interposing an adhesive, wherein both resin-molded products have a polymerized film with a radical, which is formed by activating the surface of the product, in the case of polyamide-based resin-molded products, by low-pressure plasma treatment by a microwave method using inert gas, or by activating the surface of the product, in the case of polyphenylene sulfide-based resin-molded products, by low-pressure plasma treatment by a microwave method using active gas, and then performing low-pressure plasma treatment by a microwave method using a hydrocarbon-based monomer in both cases. The resin-rubber composite can be effectively used for drum seals, automobile parts such as side cover seals for transmissions, anti-vibration rubber, resin rubber laminate hoses, and the like.

摘要： A PTFE resin seal ring in which an amorphous carbon film is formed on at least one surface of an abutting part that forms a discontinuous part of the seal ring. Since an amorphous carbon film is formed on the abutting surfaces of the PTFE resin seal ring, sticking does not occur in the abutting part even after constant load is applied at a high temperature. Thus, the PTFE resin seal ring of the present invention exhibits excellent effects of ensuring sealing properties under pressure and slidability under ordinary pressure, and is effectively used as sealing material in, for example, rotation or reciprocation, including hydraulic circuits such as automatic transmissions (A/T) and continuously variable transmissions (CVT) for vehicles.

摘要： A resin-rubber composite in which a low pressure plasma-treated polyamide-based resin molded product and a higher fatty acid salt-sulfur vulcanizable acrylic rubber composition that forms an acrylic rubber layer are directly bonded by vulcanization without interposing an adhesive. The plasma treatment of a polyamide-based resin molded product is performed by a low pressure plasma treatment method. When the plasma treatment is performed by an atmospheric pressure plasma treatment method, desired adhesion between the resin and the rubber cannot be ensured. Here, an alkoxysilane compound in rubber composition is an optional component, and the presence or absence of this compound does not affect the adhesion.

摘要： A PTFE resin seal ring in which at least one surface of an abutting part that forms a discontinuous part of the seal ring is treated by plasma modification using non-polymerizable gas under pressure conditions of 10 to 500 Pa during plasma irradiation. Since the abutting surfaces of the PTFE resin seal ring are treated with low-pressure plasma, and the state of CF bonds in the surface portion is changed, sticking does not occur in the abutting part even after constant load is applied at a high temperature. Thus, the PTFE resin seal ring of the present invention exhibits excellent effects of ensuring sealing properties under pressure and slidability under ordinary pressure, and is effectively used as a sealing material in, for example, rotation or reciprocation, including hydraulic circuits such as automatic transmissions (A/T) and continuously variable transmissions (CVT) for vehicles.
