Effect of vulcanization on the low‐strain dynamic
A similar value of change of in‐phase shear modulus with strain amplitude (G′ 0 – G′ ∞) is found for a vulcanized and unvulcanized tire tread rubber; this behavior is attributed for the breakdown of the secondary three‐dimensional carbon black aggregated network. Detailed consideration is given to other factors such as hydrodynamic, shape factor, and relaxation effects which contribute to the difference between the shear modulus of the gum rubber and the filled rubber when all ...

VULCANIZATION OF RUBBER COMPOUNDS WITH PEROXIDE CURING SYSTEMS
Vulcanization or curing is one of the most important processes in rubber technologies. During this process, plastic rubber compounds by parallel and subsequent physical and mainly chemical reactions change into highly elastic products—vulcanizates.

Investigating the effect of nanoclay/carbon black
In this study, the effect of nanoclay and carbon black on the curing system of styrene-butadiene rubber (SBR)/butadiene rubber (BR) and natural rubber (NR)/BR blends were investigated. The dispersion of nanoclay and carbon black in blends was studied under the x-ray diffraction and scanning electron microscopy.
