Document Type and Number:
Japanese Patent JP7255476
Kind Code:
B2
Abstract:
A crosslinked rubber composition for a brake hose includes ethylene α-olefin diene rubber and carbon black. The ethylene α-olefin diene rubber contains ethylene propylene diene rubber (EPDM) and ethylene butene diene rubber (EBDM), and the mass ratio of EPDM/EBDM is 30/70 to 80/20. The carbon black contains only specific carbon black exhibiting an iodine adsorption amount of 15 to 33 mg/g and a DBP absorption amount of 50 to 155 cm3/100 g. The crosslinked rubber composition exhibits a T10 of −50° C. or less as determined by a Gehman torsion test and a volume specific resistance of 1.5×105 Ω·cm or more.
