    摘要： It is an object of the present invention to provide a hydrogenated nitrile rubber composition and a drivetrain oil seal whereby seal squeal can be prevented even upon wearing away of the sealing or even under dry lubrication conditions without any grease. The hydrogenated nitrile rubber composition of the present invention comprises 100 parts by weight of hydrogenated nitrile rubber and further 10 to 55 parts by weight of wollastonite and 10 to 55 parts by weight of graphite as fillers, the total amount of the fillers being 50 to 110 parts by weight. The drivetrain oil seal of the present invention comprises a crosslinked product of the hydrogenated nitrile rubber composition.

    摘要： Seal assemblies are herein discussed. The seal assemblies can have a stiff backing ring supporting a seal ring, which is positioned adjacent an inner seal ring. In preferred embodiments, the inner seal ring is made from a material that enables the inner seal ring to absorb media particles in situ to change its particle density. This allows the seal assembly to form wearable surfaces on the fly to decrease wear on the seal ring.

    摘要： The present invention aims to provide a method for modifying a surface of a rubber vulcanizate or a thermoplastic elastomer, which can impart excellent sliding properties and excellent durability against repeated sliding motion, and allow the surface to maintain the sealing properties, without using expensive self-lubricating resins. The present invention relates to a method for modifying a surface of an object of a rubber vulcanizate or a thermoplastic elastomer, the method including: Step 1 of forming polymerization initiation points on the surface of the object; and Step 2 of radical-polymerizing a monomer starting from the polymerization initiation points to grow polymer chains on the surface of the object.
