Kinetics of Additive - Containing Sulphur - Thiazole Vulcanization of Styrene - Butadiene Rubber

The synergism of hydrofuramide and zinc stearate action was proved in SBR vulcanization.Rheometer curves reveal the favourable influence of the hydro-furamide addition both to carbon-black and the "while" mixes of SBR, obtaining thus faster vulcanizations, without the fear of the premature scorch time. In carbon black filled mixes the activation energy was found to be halved, i.e. reduced from approx.
