Researchers at Key Laboratory of Rubber and Plastics Materials and Engineering of Qingdao University of Science and Technology studied the application of naphthenic-alcohol-soluble polybutadiene-styrene rubber (SSBR) in tread rubber formulations.
The results show that compared with natural rubber (NR)*chemical glue, the loss factor (tan δ) at 0°C of SSBR*gel is larger, and the tan δ at 60°C is smaller. It can be used in tread rubber to give higher tires The anti-slip performance and low rolling resistance; SSBR and NR have good compatibility, when the SSBR/NR and use ratio is 20/80, * synthetic rubber has good physical properties; SSBR can be used in tread rubber Improves wet skid resistance of tires, grip on dry and icy roads, and reduces rolling resistance for high performance tires.
