| Abstract: |
| The modified active crumb is more stable and will change little in activity after two-year storage.When compounded with modified active crumb，the curing system needs to be adjusted.When 30—40phr level of modified active crumb is incorporated into a tread compound，85% of the tensile strength will remain；the dynamic properties，particularly the compression set will improve；the heat build-up will decrease；the processing technology will improve，including the smaller die swell duing tread extrusion，good tackness，stiff semi-product and easy assembly.The properties of the compound will be influenced by the incorporating order of the compounding ingredients. |
