vulcanisation- when sulfur atoms form cross-links between rubber molecules. vulcanised rubber is used to make car tyres and conveyor belts. :)
Charles Goodyear invented the process of vulcanisation of rubber.Before the mid-19th century, natural or India rubber was limited in its usefulness because it melted in hot weather, froze and cracked in cold weather, and tended to stick to virtually everything. Charles Goodyear was a businessman who experimented with the properties of gum elastic. He accidentally discovered the process of vulcanisation of rubber when he dropped some rubber mixed with sulfur on a hot stove. Goodyear missed out on the financial benefits of his invention as Englishman Thomas Hancock copied his idea and attained a British patent for the process before Goodyear applied for a British patent. However, vulcanised rubber was later was made into tyres emblazoned with Goodyear's name.

Sulfur is the non metal used in the vulcanization of rubber. When heated with rubber, sulfur forms cross-links between the polymer chains, improving the rubber's strength, elasticity, and durability.

Sulfur is used to cross-link the rubber. This means that the sulfur forms 'bridges' between the long chained rubber molecules. This serves to tie the molecules together, making the material harder. Think of an eraser used to correct pencil writing. That is very soft rubber. Vulcanisation turns that into the much harder material we use for car tyres. If you know anything about motor racing you will be aware that they use tyres of different hardnesses, and this is achieved by different amounts of cross-linking. If you use a lot of sulfur you can even make a rigid material known as ebonite, which is what musical instruments such as clarinets are often made of.
