Sulphur and peroxide vulcanisation of rubber compounds
Sulphur and peroxide vulcanisation of rubber compounds – overview. The application of sulphur systems leads to the forming of sulphidic cross-links between elastomer chains, while carbon–carbon bonds are formed in peroxide-curing. Both vulcanisation systems provide certain benefits to the cross-linked rubber articles, but also some disadvantages.

Sulfur vulcanization
Sulfur vulcanization is a chemical process for converting natural rubber or related polymers into materials of a variety of hardness, elasticity, and mechanical durability by heating them with sulfur or other equivalent curatives or accelerators.

Peroxide or Sulphur Cured EPDM | MacLellan Rubber
The reaction of either of these two compounds within the vulcanization process are used to link the Polymer Chains together creating Carbon-Carbon bonds (C-C) or Carbon-Sulphur bonds (C-S). Sulphur was originally used to generate the chemical reaction for vulcanizing rubber as it worked across most of the polymer types available at the time, but polymers have evolved other means of achieving the same reaction have led to Peroxide being used.

Sulfur Vulcanization - an overview | ScienceDirect Topics
SULFUR VULCANIZATION. Sulfur vulcanization can be divided into two main categories: unaccelerated and accelerated sulfur vulcanization. Unaccelerated formulations typically consist of sulfur, zinc oxide, and a fatty acid such as stearic acid, while accelerated formulations include an accelerator in the system.

Sulfur Vulcanization
Sulfur Vulcanization of Rubbers (polydienes) Vulcanization is a chemical process that converts natural rubber and other polydiene elastomers into cross-linked polymers. The most common vulcanization agent is sulfur. It forms bridges between individual polymer molecules when heated with rubber.
