The effects of carbon nanotubes(CNTs) on the properties of fluororubber rotary oil seal compound and finished product were studied. The results showed that,as the amount of CNTs increased,the curing rate and flow property of the compound decreased,the mixing energy changed little,the modulus at 100% elongation,tensile strength and tear strength of the vulcanized compound increased,tensile property and permanent compression set after heat aging increased,oil resistance and heat build-up at low frequency and small strain were changed little. Moreover,the finished oil seal which compound with 3 phr CNTs had longer service life and higher performance-cost ratio.
