Effect of Highly Modified Solution Polymerized Styrene Butadiene Rubber on Performance of Electric Vehicle Tire Tread Compound
Taking the tread formula of electric vehicle tires in production as the basic formula,different grades of solution polymerized styrene butadiene rubber(SSBR)were used for equal replacement,and the effect of SSBR microstructure on the curing characteristics,physical properties and dynamic mechanical properties of the tread compound were studied.The results showed that under the premise that the properties of the compounds were equivalent,the double-end functionalized SSBR with higher vinyl content had lower hysteresis loss,thereby lowering the rolling resistance of the tire.
