Comparison between Silica and Carbon Black in Tire Tread Formulation.

Analysis of Filler Aggregation in Compouns Using Small-angle X-ray Scattering: Effect of Functional Group Introduced into Polymer-ends of Solution-polymerized SBR

“…As shown in Figure 6, the scattering profile of Sample (i), which has silica as the filler, shows good agreement with the approximation obtained from Equation (1). Similarly, the scattering profiles of Sample (iii) and the Samples (iv) and (v) which used CB as filler showed close agreement with the approximations obtained from Equation (1).…”

“…Further work will therefore be needed to establish an analytical model capable of accurately quantifying the silica aggregation structure. Table 4 and Figure 7 summarise the results from analysis of the scattering profiles of the silica compound samples, Samples (i) and (iii), and the CB compounds samples, Samples (iv) and (v), using Equation (1). Table 4 lists the parameters relating to the radius of the filler primary aggregates found by calculation: R md is the most frequent value in the logarithmic normal distribution, R av is the mean, and R fi is the radius of the primary particles of silica or CB used in experiments that have been reported in the literature.…”

“…Rubber materials in general are composites of natural or synthetic rubber and fillers, etc, and their physical properties depend not only on the volume fraction of filler but also its state of dispersion. An example is the effect that the carbon black (CB) and silica used as fillers in automotive tyre rubber have on tyre properties [1,2]. Among the various properties of tyre rubber, a reduced rolling resistance is associated with improved vehicle fuel consumption and is hence identified as a key property for fuel economy tyres.…”

Materials Technology for Reducing Rolling Resistance

“…4 shows the results from evaluation of the silica compounding of different S-SBRs in which the modifier or microstructure were varied (ref. 17). The 50°C tan δ was greatly affected by microstructure, relatively modest effects being obtained with the modifier and T g .…”

Filler Effects on Temperature Dependence of Viscoelastic Properties of Filled Rubbers

“…We have, however, confusion still now. For example, Kobayashi et al have reported that the temperature dependence of the shift factors on carbon black and silica filled SBRs showed no dependence on kind of fillers 4) , while Mouri et al have reported that it showed the dependence 5) .…”
