Rubber in natural form is a long polymer with a strong tendency to swallow and a very small capability to maintain its form in front of temperature changes. As all polymers it is formed by very long chains formed by repetition of the same molecule, called the monomer. The chain can be cross linked by introducing chemical bonds either between different parts of the same chain or between different chains.
By cross linking natural rubber with sulfur (a process called vulcanization) the rubber becomes much more elastic, that is able to return to its original shape after deformation, and much more resistant to temperature changes. This means that a chain of three sulfur atoms are structured like a bridge bonding different parts of a chain or of different chains.
At 2 to 3% cross linking a soft rubber, that no longer suffers stickiness and brittleness problems on heating and cooling, is obtained. At 25 to 35% cross linking a rigid hard rubber product is formed.
Yes, rubber bands typically contain sulfur. Sulfur is commonly used in the vulcanization process of rubber, which enhances its elasticity and durability.

Sulfur is mainly used in the production of sulfuric acid, which is a key ingredient in various industrial processes such as fertilizers, chemicals, and batteries. It is also used in the production of rubber, paper, and pharmaceuticals. Additionally, sulfur is used in the vulcanization of rubber to improve its strength and durability.
The vulcanization of rubber is a chemical process where you convert rubber, or other related polymers, into a more durable material by way of the addition of sulfur. The reason why you can not use any other element to do this is because other elements do not produce the same results.
Sulfur is used in the production of sulfuric acid, which is widely used in industry for many applications including fertilizers, batteries, and chemical manufacturing. Additionally, sulfur is used in the vulcanization of rubber to improve its durability and resistance to wear.
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.

vulcanisation- when sulfur atoms form cross-links between rubber molecules. vulcanised rubber is used to make car tyres and conveyor belts. :)

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.
i have no idea at all that is why i typed it in

rubber was not very useful until vulcanisation was discovered . this process can improve its elasticity and strength .
