AB  - In this research, the Mooney viscosity, crosslink density and cure characteristics of the treated
Silane–Carbon Black/Nanocalcium Carbonate (Si–CB/NCC) reinforced Natural Rubber/Styrene Butadiene Rubber
(NR/SBR) composites were investigated. The results showed that the addition of treated CB/PCC at different
concentration of silane coupling agent increases the crosslink density where the superior crosslink density of
composites was achieved at 4 wt.% of silane treatment (NR–SBR/CB–NCC4–Si69). At this composition an
increment of crosslink density is about 11% as compared to the untreated filler–BR/SBR composites. A positive
correlation between crosslink density and Mooney viscosity behaviours has been shown that by increasing
the 3D–network structure, it increases the viscosity and compactness of the rubber composites structures. The
formation of optimum active sites on the CB and PCC filler surfaces led to accelerate the vulcanisation process
about 17% as compared to untreated filler–NR/SBR composites where these active sites of fillers surface led to
an increase of the adhesion at the interface between treated fillers and NR/SBR matrix. It is noted that sufficient
amount of silane is required to improve the overall properties because excessive silane content gave the
plasticising effect to the composites structure, thus, resulting in the reduction of other properties.
