Vulcanizing agents other than sulfur are peroxides, resins and metal oxides used to form cross-links in the rubber [30]. Unsaturated elastomers (C=C) can be vulcanized with sulfur, while the saturated elastomers (C-C) cannot be vulcanized with sulfur but are vulcanized by peroxides. The cross-linking reactions mainly occur at the C=C bonds.Web
