HIGH-PRESSURE RUBBER HOSE |
摘要 |
<p>A high-pressure rubber hose has a reinforcing layer embedded therein, has at least an outer layer thereof formed of the vulcanization product of an ethylene-.alpha.-olefin-diene copolymer rubber (hereinafter referred to as "EPDM" for short), and is adapted to be used as fastened by staking to a sleeved joint. The high-pressure rubber hose requires that the ethylene/.alpha.-olefin ratio (by weight) in the EPDM should fall in the range of 45/55 to 58/42 and that the Mooney viscosity of polymer (ML1+4 100.degree.C) of the EPDM should fall in the range of 120 to 250. This high-pressure rubber hose manifests dynamic resistance to ozone and mechanical properties such as tensile strength to advantage without any sacrifice of the compression permanent set necessary for the sake of the sealing property.</p> |
