Curing agents. The generally used curing agents are sulfur, peroxides, and metal oxides. These materials are used to cross-link the rubber matrix; these cross-links form different bonds, such as carbon–carbon, carbon–sulfur, and sulfur–sulfur linkages. The bond energy also depends on the type of cross-linking formed in the elastomer matrix.

curing agent above 300 Deg. F in the presence of air may cause slow oxidative decomposition; above 500 Deg. F, polymerization may occur. Some epoxy resins can produce exothermic reactions which in large masses can cause runaway polymerization and charring of the reactants. Fumes and vapors from these thermal and chemical decompositions

vulcanization

Vulcanization

For example, early rubber tube tires in the 19th century would grow sticky on a hot road, until debris would get stuck in them and eventually the tires would burst. Charles Goodyear, in the 1830s, was working to improve those tube tires. He tried heating up rubber in order to mix other chemicals with it.

what do the terms "heat curing" and "post-curing" mean?

What do the terms "heat curing" and "post-curing" mean?

Post Curing. Mold Making – Post curing any mold rubber will enhance the physical and performance properties of the mold rubber. Procedure: following a normal cure cycle for a mold rubber (generally 16 to 24 hours), the cured mold can be exposed to mild heat (150°F / 65°C) for 4 to 8 hours.
