<p>A hydrogenated nitrile rubber composition capable of providing a cross-linked product having a 20% modulus of 10 MPa or more and a thermal conductivity of 0.4 W/m . K or more at 25 DEG C, which comprises 100 parts by weight of hydrogenated nitrile rubber having a bound acrylonitrile content of 40% or more, a polymer Mooney viscosity ML1+4 (100 DEG C) of 75 or less (median) according to JIS K-6395 and iodine value of 23 or less (median), and not less than 110 parts by weight in sum total as a filler consisting of carbon black and other gas shielding fillers, can be effectively used as a molding material for sliding application or for a static sealing member for highly permeable gas, because of distinguished carbon dioxide gas shieldability, heat resistance, wear characteristics, etc.</p> |
