| Abstract: |
| The change of the apparent shear stress in the HAF loaded NR compound with different level of high aromatic oil，4#rubber oil and paraffin oil was determined by MPT(Monsanto Processiblity Tester)at the temperature of 70～130 ℃ and at the apparent shear rate of 50～631 s-1.For the system with the first group of flow curves，the data were processed with a computer before a formula for softening index(SI) and loading level of softener(P) was established to show the influence of the temperature and the apparent shear rate on the SI-P relation. |
