Concurrently, heat is supplied via heating platens or a vulcanising machine, activating the vulcanising agent. This leads to the chemical bonding and curing of the rubber layers. Cooling: Post-vulcanisation, the spliced area is allowed to cool gradually, a phase critical to preserving the splice's strength and integrity.

Vulcanization is a kind of chemical reaction between sulphur, or another agent, and natural rubber.It makes cross-links between the molecular chains in the rubber. The reaction is not reversible. Charles Goodyear discovered it in 1839.. The purpose of this is to harden the rubber so it does not melt or soften in warm temperatures.This hard rubber can keep its shape when …
