- Untreated latex consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Vulcanisation is the process by which the latex is heated with sulphur to create molecular crosslinks between the long rubber molecules. Increasing the sulphur content increases its hardness and tensile strength.

Jul 24, 2021 · Vulcanization or vulcanisation (British) is a process of hardening rubber using chemicals and (usually) heat. Originally, vulcanization described the treatment of natural latex rubber with heat and sulfur. While this remains the most common type of vulcanization, the process also applies to synthetic rubber and may involve other chemicals. History
Vulcanization is a critical process in the rubber industry that enhances the mechanical properties and durability of rubber materials. It is widely used to transform raw natural rubber or other polymer materials, such as synthetic rubber, into more robust and versatile products.
Dec 10, 2014 · The chemistry that occurs under the conditions of vulcanisation is such that the heat and pressure applied allows the sulphur atoms present to attack the double bonds of the carbon atoms in the isoprene strands and bind to them.
Apr 25, 2017 · The process of hardening rubber is known as vulcanization. This method was discovered accidentally in the early 19th century and then developed in order to find some way to make latex, the natural excretion of rubber trees, more rigid and resistant to abrasion.
The latex is a sticky, milky colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into rubber ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup.

The main polymers subjected to sulfur vulcanization are polyisoprene (natural rubber) and styrene-butadiene rubber (SBR), which are used for most street-vehicle tires. The cure package is adjusted specifically for the substrate and the application.
