Abstract
Mooney viscosity, cure characteristics, tensile properties, tear strength, rolling resistance property, abrasion resistance ,dynamic cutting property and other properties of the homogeneous rare earth IR/NR blend were investigated, and compare to Russian SKI-3/NR blend, SKI-5/NR blend and NR. The results showed homogeneous rare earth IR/NR blend has similar or even better properties compare to SKI-3/NR blend, SKI-5/NR blend and NR. The tire products made by these rubbers have similar performance. The tires passed the China National Quality Supervision and Inspection Center of rubber tire certification, which met the requirements of all-steel TBR tire. The homogeneous rare earth IR prepared by Petro China Jilin Petrochemical Company could part instead of NR using in all-steel TBR tire.
