| Abstract: |
| The influence of curing systems on the curing behavior，physical properties and thermal aging property of HNBR/CR blend （blend ratio 70/30） was investigated.The results showed that，when the curing system of main curing agent DCP and co-curing agent TAIC was used，the scorch time of HNBR/CR blend was longer，elongation at break was higher，tensile set at break was lower，and thermal aging property was better.When the addition levels of DCP and TAIC were 5 and 3 phr respectively，the curing rate of HNBR/CR blend washigh，and processing safety，oilresistance，comprehensive physical properties and thermal aging property were good. |
