摘　　要：The air-tightness and conductivity of NR/CSF and NBR/CSF vulcanizates were studied. The results showed that the carbon black bound rubber content of NR or NBR compounds with 50 phr of CSF were higher than those with the same amount of acetylene black(ACET) or high abrasion furnace black(HAF). In addition, the yield strength(Ty) and tensile strength(Tb) of their compounds were also higher than those of the latter, and the more the loading of carbon black, the higher the difference. The air-permeability of NR filled with 50 phr of CSF was less than that of NR filled with 50 phr of HAF, and close to that of IIR. The volume resistivity of NR/CSF or NBR/CSF vulcanizate was obviously lower than that of NR/ACET or NBR/ACET one. Moreover the volume resistivity of vulcanizate decreased with increasing carbon black amount. The electric conductivity of NBR filled with CSF or ACET was better than that of NR.The air-tightness and conductivity of NR/CSF and NBR/CSF vulcanizates were studied.
