Carbon black ( CB ) and precipitated silica are two major reinforcing fillers in rubbers. CB /silica hybrid filler is also widely used in rubbers to provide balanced properties. CB /silica‐hybrid‐filler‐filled styrene‐butadiene rubber ( SBR ) containing naphthenic oil ( NO ), soybean oil ( SO ) and norbornylized SO ( NSO ) was investigated. The swelling and curing behavior and rheological, mechanical, thermal, aging and dynamic properties were studied and compared with earlier reported data on CB ‐ or silica‐filled SBR . NSO provides better scorch safety and faster cure than SO . Compared with NO , the addition of SO and NSO enhances the thermal stability and aging resistance of SBR vulcanizates. SBR / NSO vulcanizates with hybrid filler exhibit a higher tensile and tear strength than SBR / NO and SBR / SO vulcanizates. A synergistic effect in the abrasion resistance of vulcanizates containing the hybrid filler is observed. An increase of sulfur content in the hybrid‐filler‐filled SBR / NSO vulcanizates provides further improvement in abrasion resistance, wet traction and rolling resistance. © 2017 Society of Chemical Industry
