Abstract
A fluororubber composition includes a polyol-crosslinkable fluororubber, a crosslinking accelerator, a polyol crosslinking agent and calcium hydroxide, with the crosslinking accelerator having a specific weight ratio relative to the polyol crosslinking agent, and is heat treated under specific conditions to give a low-friction fluororubber crosslinked product that is well balanced and excellent in properties such as low frictional properties, low tackiness and low resilience properties and that is favorably employed as rubber vibration insulators and impact-absorbing stoppers represented by HDD stoppers.
