In this study, the cured NR and waste tire tread powder were reclaimed using rubber reclaiming agent RV2. It was found that when the amount of RV2 was 2.5 phr, good reclaiming result was achieved for cure NR by mixing in plasticator at 60 ?C for 5 min and milling for another 5 min. For recycled powder of tire tread compound, the optimal amount of RV2 was also 2.5 phr, and after mixing in a high speed mixer, the rubber powder was effectively reclaimed through mechanical shear using either twin-screw extruder or single-screw extruder. Further test results revealed that the compatibility between the reclaimed rubber and NR was good, and the physical properties of the NR compound with 20~30 phr of reclaimed rubber were good. Moreover, the production process of RV2 was simple without waste water or waste gas.
