Material Matters: Vulcanised Rubber Sole Construction
The original method of vulcanisation, and still the most common, is to mix sulphur with natural rubber and then heat it. The sulphur changes the chemical structure of the rubber, creating crosslinks between polymers to make them stronger and more durable.

Adhesive Tapes Selection Guide | Engineering360
Vulcanization is a chemical treatment that adds sulfur and heat to crosslink the rubber. Natural rubber is an elastic substance that is obtained by coagulating the milky juice of any of various tropical plants. Essentially, natural rubber is a polymer of isoprene and is prepared as sheets and then dried.

Despite electric heat being 100 per cent efficient, most precise to control, and lowest maintenance; the cost per kilowatt-hour makes them expensive for your use. And because rubber vulcanizing cannot be done in an air atmosphere, you mostly use steam. Two types of autoclaves are in common use – Non-jacketed and Jacketed.

Vulcanization | rubber manufacturing | Britannica
Vulcanization, chemical process by which the physical properties of natural or synthetic rubber are improved; finished rubber has higher tensile strength and resistance to swelling and abrasion, and is elastic over a greater range of temperatures. In its simplest form, vulcanization is brought about by heating rubber with sulfur.

Charles Goodyear and the Vulcanization of Rubber
According to biographers, while working at the Eagle India Rubber Company, Goodyear accidentally combined rubber and sulfur upon a hot stove. Much to Goodyear’s surprise, the rubber didn’t melt. And, when he raised the heat, it actually hardened. Naugatuck Emerges as Industry Hub

vulcanisation. Unlike natural rubber,in the vulcanisation of styrene butadiene rubber,a copolymer,the crosslink formation is relatively slower and therefore requires higher amounts of accelerator and lower levels of sulphur. This is attributed mainly to the lower number of double bonds, which are responsible for crosslinking with sulphur. The

Vulcanization | Article about vulcanization by The Free
Hard rubber is vulcanized rubber in which 30% to 50% of sulfur has been mixed before heating; soft rubber contains usually less than 5% of sulfur. After the sulfur and rubber (and usually an organic accelerator, e.g., an aniline compound, to shorten the time or lower the heat necessary for vulcanization) are mixed, the compound is usually placed in molds and subjected to heat and pressure.

What is the importance of sulphur in the vulcanization
Rubber is made up of hydrocarbon chains, basically carbon and hydrogen. These chains slide over one another and get tied to one another which leads to natural rubber being sticky. Now when we vulcanize rubber by using sulphur, the sulphur reacts
