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.

Do rubber bands contain sulfur?
rubber bands do contain sulfur

What element is used in match heads and fungicides?
sulfur is the element that is used in insecticides.
Why not any other element is used for vulcanization of rubber?
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.
What is the element used in vulcanization of rubber?
Hi there :D Rubber is a hydrocarbon therefore hydrogen and carbon. Also some rubber is hardened. This is called vulcinisation and it uses sulphur. If you would like a free lecture on this or just dancy a chat do not hesistate to call: 07801511359 Many thanks James Cockerton
What is the non metal used in vulcanisation of rubber?
sulfur is used
What is the formation of synthetic rubber by cross linking with sulfur?
Vulcanisation
What element is used in Vulcanisation?
Sulfur.
What did rubber vulcanization do?
vulcanisation- when sulfur atoms form cross-links between rubber molecules. vulcanised rubber is used to make car tyres and conveyor belts. :)

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.
How is rubber made tougher?
Vulcanisation- addition of sulphur
What process involves treating rubber to harden it?
Vulcanisation.
When was the vulcanisation of rubber made?
i have no idea at all that is why i typed it in
The process of curring rubber named after the Roman god of fire?
Vulcanisation
What v can change the properteies of rubber?
Vulcanisation - adding sulphur and heat changes rubber - to make tyres for example
Why was vulcanized rubber important?
rubber was not very useful until vulcanisation was discovered . this process can improve its elasticity and strength .
