CURING(VULCANIZING)AGENTS
Rubber is generally vulcanized with the addition of sulfur.
Instead of sulfur, vulcanization can be done by the use of chemical compounds containing oxygen or sulfur which make linkage between the molecules of rubber to give high elasticity.
Those materials are called curing(vulcanizing)agents, or also widely known as cross-lnking agents.
