| Abstract: |
| The effect of the polymer blending ratio，the filler type，and the sulfur，accelerator，filler and softener levels on the curing behaviour of EPDM/IIR blend was investigated.The results showed that the t90 shortened and the maximum torque MH increased as the blending ratio of EPDM/IIR increased；t10 shortened，t90 extended and MH increased as the sulfur level increased；the increase of CZ level had little effect on the curing behaviour of blend；for the N220 filled blend，t10 and t90 were shorter，but MH was greater；t90 extended and both minimum torque ML and MH increased as the N220 level increased；and t90 shortened and MH decreased as the level of softener vaseline increased. |
