Effect of hybrid carbon black/lignin on rheological, mechanical and thermal stability properties of NR/BR composites

This study investigated the effect of hybrid carbon black/lignin on the rheological, mechanical and thermal stability of NR/BR composites. Three types of lignin, namely, Kraft lignin (KL), organosolv lignin (OL) and soda lignin (SL) were incorporated into rubber matrix at the filler loadings of 5–20 phr, where the total filler content was fixed at 50 phr. Based on the performance of the three types of lignin, the KL and OL-filled NR/BR...
