We want to promote our development of syntheticrubber grades for tire according to the cooperation with the scientificresearch institutes and famous tire enterprises which have technical advantagesin the processing and application or evaluation of tire rubber. We hope thecommercial popularizing of our grades (mainly SSBR and SIIR for highperformance tire) can be promoted through the teamwork in performanceevaluation, tire formula evaluation, tire trial-manufacture and mileage benchtest
