摘要： A hydrogenated nitrile rubber composition, which comprises 100 parts by weight of hydrogenated nitrile rubber having a Mooney viscosity ML1+4 (100° C.) of 100 or less, an acrylonitrile content of 30-50%, and an iodine value of 28 or less, 60-250 parts by weight of carbon fibers, and 12-70 parts by weight of a polyfunctional group-based cocross-linking agent having a molecular weight of 150-500, and a viscosity (20° C.) of 3-120 mPa·s. The composition can further contain 30-150 parts by weight of carbon black and/or 60 parts by weight or less of graphite. The resulting hydrogenated nitrile rubber composition enables higher loadings of carbon fibers without lowering the kneadability and the molding processability, thereby improving the abrasion resistance of seal materials cross-linking molded from the composition.

摘要： Disclosed is a lip seal for water pump made of a rubber-like elastic material, fixed to a housing as a fixed side and in sliding contact with a shaft rotating relative to the housing; the lip seal being obtained by vulcanization-molding of a rubber composition comprising 100 parts by weight of the rubber-like elastic material, 1 to 150 parts by weight of a reinforcing filler, 5 to 90 parts by weight of a non-reinforcing filler having an average particle diameter of 1 μm or more, 0.1 to 5 parts by weight of a coupling agent, 1 to 15 parts by weight of a co-crosslinking agent, and 0.5 to 10 parts by weight of an organic peroxide. The lip seal for water pump provides a materially solution, rather than a structural solution, to prevent softening and volume swelling of the rubber-like elastic material and the generation of deposits in the rotating shaft, which are problematic for rotation torque and LLC resistance.

摘要： Disclosed is an EPDM composition for molding sealing materials, containing a plasticizer; the plasticizer being a paraffinic oil or naphthenic oil in which the absolute value of the difference between its SP value (solubility parameter; determined by Small's formula) and the SP value of EPDM is 0.3 (cal/cm3)1/2 or less; and the composition being free of an ether ester plasticizer. The EPDM composition for molding sealing materials has the following excellent effects. Because a paraffinic oil or naphthenic oil that is compatible with EPDM and has an absolute value of the difference between its SP value and the SP value of EPDM of 0.3 (cal/cm3)1/2 or less is used as the plasticizer, a peroxide crosslinked product of the EPDM composition does not form defects that cause the starting point of blisters even when it is subjected to extraction by being brought into contact with HFO-1234yf. Accordingly, the peroxide crosslinked product, when used as a sealing material, particularly a compressor sealing material, exhibits excellent blister resistance to a hydrofluoroolefin refrigerant, such as HFO-1234yf.
摘要翻译： 公开了一种用于模塑包含增塑剂的密封材料的EPDM组合物; 增塑剂是其SP值（溶解度参数;由Small公式测定）与EPDM的SP值之差的绝对值为0.3（cal / cm 3）1/2以下的石蜡油或环烷油; 并且该组合物不含醚酯增塑剂。 用于模制密封材料的EPDM组合物具有以下优异的效果。 由于使用与EPDM相容并且其SP值与EPDM的SP值的绝对值为0.3（cal / cm 3）1/2以下的石蜡油或环烷油作为增塑剂，因此使用过氧化物 EPDM组合物的交联产物即使在通过与HFO-1234yf接触进行萃取时也不会形成引起起泡点的缺陷。 因此，当用作密封材料的过氧化物交联产物，特别是压缩机密封材料时，对HFO-1234yf等氢氟烯烃制冷剂具有优异的耐起泡性。
