Vulcanizable partially hydrogenated nitrile rubber composition containing partially hydrogenated unsaturated nitrile-conjugated diene copolymer sulfur vulcanizer and tellurium dithiocarbamate vulcanization promotor

摘要

A vulcanizable rubber composition including a partially hydrogenated unsaturated nitrile-conjugated diene copolymer having an iodine value of smaller than 25, a sulfur vulcanizer and a tellurium dithiocarbamate compound as a vulcanization promotor. This rubber composition provides a vulcanizate having reduced heat build-up, reduced compression set and high mechanical strength.
