Study on Properties of EPDM/reclaimed NR Blend reinforced with different Carbon Black

Effects of five kinds of carbon black with different particle size on mechanical properties of EPDM/reclaimed NR blend were studied.It was found that the mechanical properties were improved with the decrease of carbon black particle size and the increase of their structure degree.But if carbon black particle size was too small,the mechanical properties would begin to decrease;Carbon black N330 had the best reinforcement effect among the 5 kinds of carbon black.
