greater tan δ value of the rubber composites in the region of À20 to 10
C can be
accounted to figure out the superior anti-skid properties of the rubber composites
under wet conditions and lower tan δ value of the rubber materials in the range of
50–60
C indicates the low rolling resistance of the rubber stuffs. We can see from
the respective figures that the tand values of the EG and i-MG filled SBR/BR based
composites in the region of À20 to 10
C were higher than tand values of the only
BR based nanocomposites. So, after the homogeneous mixing of SBR with BR in
the presence of different nanofillers, the anti-skid property under wet conditions of
the BR vulcanizates was significantly improved. At the same time, rolling resistance of the SBR/BR based nanocomposites was lowered (lower tan δ values of the
