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.

What is the non metal used in vulcanisation of rubber?

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.

Why use sulfur in vulcanisation?

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.

Do rubber bands contain sulfur?

Yes, rubber bands typically contain sulfur. Sulfur is commonly used in the vulcanization process of rubber, which enhances its elasticity and durability.
