Abstract

The effect of ultra-fine fully vulcanized powdered styrene-butadiene rubber(UFPSBR) on the properties of NR/SBR/BR tread compound was investigated.The results showed that,compared with the tread compound without UFPSBR,the NR/SSBR/BR tread compound with 2~3 phr UFPSBR had lower tensile strength,better wear resistance and wet skid resistance,and lower heat build-up;the NR/ESBR/BR tread compound with 1~2 phr UFPSBR had higher tensile strength,better wet skid resistance,similar rolling resistance,and decreased wear resistance.
