Unformatted text preview: Figure 1.3 Illustration of the function of silane coupling agent. 1.4 Crosslinking Mechanisms and Cure Kinetics 1.4.1 Curing of Natural Rubbers Peroxide and sulfur are the most widely used crosslinking agents for uncured natural elastomers. The chemical reaction consisting in the addition of sulfur to the double bonds of the rubber molecules are always involved in the vulcanization of rubber with sulfur, which constantly forms the three dimensional networks (Lewis, et al. 1937). For peroxide curing, the free radical produced by peroxide is the driving force for peroxide crosslinking, which is much faster than sulfur cure. Free radicals are atoms or molecular...
